Conclusion- hyperlipidemia.

High blood cholesterol is a major risk factor for heart disease, and heart disease is the leading cause of death in the United States. Population health approaches have attempted to reduce the prevalence of hyperlipidemia through screening and by increasing public awareness of high cholesterol and strategies for reducing it. Physicians are in a unique position to counsel, prevent and medically manage patients, families and communities regarding high cholesterol. While counseling on cardiovascular risk, healthy lifestyle changes, and medications, they additionally face the challenges of caring for multicultural patients who speak various languages, have wide ranging socioeconomic status and unique ways of understanding illness and healthcare.

The 2013 ACC/AHA guidelines on lipids offer a perspective on lipid management using a more rigorous approach, based on RCT evidence, than in years past. The informed practitioner will be aware of past and present practices, the evidence they are based on, and acknowledge that some uncertainty and disagreement (among physicians, societies, and researchers) about management of cholesterol will remain for the time being.

Lipids are organic molecules that play important roles in microbiology as energy storage molecules, structural components, and signaling molecules.

In terms of energy storage, lipids serve as a reserve of energy that can be mobilized by cells as needed. For example, bacteria can store energy in the form of fatty acids, which can be broken down to produce energy during times of stress or when other energy sources are scarce.

Lipids also serve as structural components in microorganisms. For example, the cell membranes of bacteria and other microorganisms are composed of lipids, which play important roles in maintaining the integrity and fluidity of the cell membrane. In addition, some microorganisms produce lipids in the form of biofilms, which can help the microorganisms adhere to surfaces and form protective communities.

In addition to their structural roles, lipids also play important roles in cell-to-cell communication and interaction in microorganisms. For example, some bacteria produce lipids that act as signals to regulate processes such as quorum sensing, in which bacteria coordinate their behavior based on the density of the population.

In conclusion, lipids play important roles in microbiology as energy storage molecules, structural components, and signaling molecules. Understanding the roles of lipids in microorganisms is crucial for understanding microbial metabolism, behavior, and interactions with the environment.

Essay on Lipids

Lipids Lipids are fats, oils and waxes, organic compounds containing carbon, hydrogen and oxygen. The same three elements are involved in the structure of carbohydrates, but the amount of oxygen in the molecule present is much less than in carbohydrates. Lipids are insoluble in water but soluble in organic solvents such as acetone and ether. They are relatively small molecules compared to the polysaccharides, but because they are insoluble they tend to join together to form globules. Lipids can be split into the following They are glycerol , fatty acids, oils, fats, waxes, phospholipids and triglycerides (ester). The properties of the fats are, · Fats are insoluble in water but …show more content…

Fatty acid molecules are much larger than those of glycerol and consist of long non-polar hydrocarbon chains with carboxyl group (COOH) at the end. Fatty acids are divided into 2 groups, saturated (single bond carbon atoms) and unsaturated (double bond between carbon atoms) fatty acids. Fatty acids play an important role in cells. Fatty acids can be broken down and oxidized to release energy; they can also be converted into phospholipids, which are important constituents of cell membranes. Triglycerides are the commonest lipids in living organisms and their primary importance is as energy stores. As I have said they are compact and insoluble and can be stored at very high concentrations in cells (they do not have any osmotic effect on the cell), in cells they occur as small oil droplets suspended in the cytoplasm. Triglycerides release twice the amount of energy as per gram of carbohydrates, but also when triglycerides are broken down metabolic water is produced which is very important for animals that live in arid countries. (Metabolic water is water produced when organic molecules are oxidised in a reaction. Oils are the major food stores in many seeds (sunflower, rape) and fruits (palm, olive). Phospholipids are same in certain way to lipids but the difference is that they are esters of fatty acids and glycerol, but one

Lipids make up the outer membranes of cells, while carbohydrates can be used to make exoskeletons. Furthermore, the glycerol heads in lipids are made of carbon, oxygen and hydrogen which are attached to long hydrocarbon tails. Carbohydrates must have this ratio of carbon, hydrogen and oxygen:(CH2O)n They both contain a lot of energy. Another similarity is that both carbohydrates and lipids can be used to provide structure. Both are broken by hydrolysis and combined using dehydration

Lipids are fats and oils and have no true monomers, but they are made of glycerol and fatty acids. Lipids can be saturated, which means that every carbon has a single bond and has the maximum number of hydrogens possible, and they can be unsaturated, which means the carbons can have double bonds and not the maximum number of hydrogen. Lipids store energy, act as insulation to organisms, and protect organs from injury. Nucleic acids are made of monomers called nucleotides, and they make up the DNA and RNA of an organism. They have the information needed to produce proteins needed for a person’s body.

The fatty acids are then purified by distillation and neutralized with an alkali to produce soap and water. The fats and oils used in soap-making come from animal or plant sources. The four basic soaps used in this procedure were made using olive oil, vegetable oil, vegetable shortening, and lard. Each fat or oil is made up of a distinctive mixture of several different triglycerides. In a triglyceride molecule, three fatty acid molecules are attached to one molecule of glycerin. There are many types of triglycerides; each type consists of its own particular combination of fatty acids. They are weak acids composed of two parts: A carboxylic acid group consisting of one hydrogen (H) atom, two oxygen (O) atoms, and one carbon (C) atom, plus a hydrocarbon chain attached to the carboxylic acid group. Generally, it is made up of a long straight chain of carbon (C) atoms each carrying two hydrogen (H) atoms. The carboxylate end of the soap molecule is attracted to water. It is called the hydrophilic end; this end of the fatty acid chain prefers water. The hydrocarbon chain is attracted to oil and grease and is the hydrophobic end. However, when soap is presented to hard water which is water containing minerals, such as calcium, magnesium, and seldom minerals like iron. Soap produces what is known as soap scum, or residue from the

Animal Nutrition: Distinguish Macronutrients and Micronutrients

A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturateddepending on the detailed structure of the fatty acids involved. Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans-isomer bonds; these are rare in nature and in foods from natural sources; they are typically created

Carbohydrates are the body’s primary source of energy. Without adequate carbohydrates, a person may feel fatigued and weak, as the body looks elsewhere for sources of energy. A severe lack of carbohydrates can deprive critical bodily organs the necessary energy to properly function. Lipids are naturally occurring organic compounds that include fats and oils. An excess of some lipids can increase the chances of certain health problems, lipids are vital nutrients to a healthy body. Lipids are necessary for the absorption of fat soluble vitamins. A diet too low on lipids lowers the level of good cholesterol, decreases the body’s energy level and can disturb the body’s formation of cells and cell functions.

High Cholesterol Essay

High cholesterol is one of the most common diseases that occur in today's society. According to Centers for Disease Control and Prevention, 71 million American adults have high LDL "bad" cholesterol. When cholesterol levels are normal, they normally do not harm the body since cholesterol can be beneficial to the body. However, if excess amounts of cholesterol are in the body, it can become a threat. "Cholesterol is a waxy substance that plays an important role in building cell membranes and sex hormones" (Overview). The certain types of food you consume on a daily basis may affect the cholesterol levels in your blood. There are two types of cholesterol, which is your HDL (high density lipoprotein), "good", cholesterol, and your LDL (low density lipoprotein), which are the "bad" cholesterol. It is critical that an individual maintains his or her cholesterol levels because he or she can increase their risk of cardiovascular disease. LDLs are known to carry cholesterol into your arteries and clog them, which can cause strokes and heart attacks. On the other hand, HDL, help eliminate cholesterol from the arterial vessels and transport it to the liver, which is then defecated with body waste. According to Sroda, an individual's total cholesterol should be less than 200, LDL levels should be less than 130,

“Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat, transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism, which help aid in the chemical reaction process. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions (Dowshen). Metabolism is a constant process that begins when we're born and ends when we die. It is a vital process for all life not just humans, and

Types of Lipids, Their Structures, Functions in the Body, and Health Effects

Lipids have a broader spectrum of structures and compositions, which is why they are defined based on their physical properties. They are commonly referred to as organic molecules that do not dissolve in water but dissolve in non-polar solvents. Lipids are categorized into three types including triglycerides, phospholipids, and sterols (Murphy 326). Lipids play three important roles in the body including; they function as the structural components for cell membranes, serve as energy storehouses, and work as key signaling molecules. This discussion analyzes each of the three types of lipids, their structures, their role in the body, and their overall health effects.

Types and structure of Lipids

Triglycerides make up over 95% of the lipids in foods and the body. They are common in fried foods, butter, cheese, vegetable oil, whole milk, and cream, and fatty meats. Naturally occurring triglycerides are obtained in foods like olives, nuts, corn, and avocados (Feingold and Peter 281). Fats and oils are the common names for triglycerides, where fats are lipids in the form of solid whereas oils are lipids in the form of liquid. The structure of a triglyceride comprises glycerol and three fatty acids. The glycerol is the backbone comprising of three carbon, while fatty acids are the longer chains of carbon molecules linked to the glycerol backbone. Fatty acids exist in different types, but triglycerides might contain a mixture of some or all of them. They are categorized depending on the length of carbon chains and the extent of saturation. Different foods contain different amounts of fatty acids, which determines health risks.

Phospholipids make up around 2% of the dietary lipids. They play the important role of building the protective barrier for cell membranes. Essentially, phospholipids are synthesized to form organelle and cell membranes. Phospholipids also form structures within the blood and body fluids where fat is enclosed and transported across the bloodstream. Phospholipids contain a glycerol backbone like the triglycerides but only comprise two fatty acid molecules linked to the glycerol backbone (Feingold and Peter 285). The structural difference between a phospholipid and a triglyceride is the position of the third carbon. Instead of fatty acid, the phospholipid contains a phosphate group. For this reason, phospholipids are water-soluble and fat-soluble.

Sterols are the least popular types of lipids commonly referred to as steroids. Sterols have chemical structures that are completely different from those of triglycerides and phospholipids. Most sterols comprise multi-ring structures that look like chicken wire. They are considered complex in terms of structure, containing interlinking carbon rings, some side chains of carbon, attached oxygen, and hydrogen. Cholesterol is the commonly known form of sterol which is further classified as high-density lipoprotein (HDL) and low-density lipoprotein (LDL). Primarily, HDL is considered good cholesterol since it takes cholesterol to the liver where it can be eliminated from the bloodstream before it can build up to the arteries (Gurr and Harwood 202). LDL, on the other hand, is considered bad cholesterol since it takes cholesterol directly to the arteries leading to atherosclerosis that can cause stroke or heart disorders.

Functions of Lipids

Lipids primarily serve as energy reserves proving the body with energy as and when it is required. Compared to other body cells that only store a limited supply of fats, specialized fat cells are capable of expanding to store huge supplies of fats. For example, glucose is stored in the body as glycogen and serves as a ready source of energy. The human body requires energy to empower the muscles for all kinds of physical activities (Murphy 352). Even children require energy to play and engage in all sorts of physical exercise. Without energy reserves, athletes wouldn’t be able to go down the track while dances wouldn’t be able to showcase their moves or keep their legs moving throughout the performance.

In addition to being energy storehouses, lipids function as regulating and signaling agents. For example, triglycerides control and maintain constant body temperature. For this reason, those with an insufficient amount of fats in the body feel colder, are always fatigued, and suffer from pressure sores on the skin due to fatty acid deficiency (Murphy 371). Fats also play a crucial role in maintaining tissue structure, sustaining memory storage, and facilitating nerve impulse transmission. In the brain, lipids help in the formation of nerve cell membranes that insulates the neurons and provide for the signaling of electrical impulses across the brain.

General body insulation and protection is another key function of lipids. Vital body organs such as the skin, liver, kidney, brain, and heart are surrounded and insulated by visceral fats. Surprisingly, 60% of the brain comprises fats, which shows the main structural role that fats play in the body (Murphy 418). The fat layer underneath the skin protects the body against extreme temperatures and maintains the internal body temperature. In the buttocks and hands, the fat layer prevents friction when these parts get into contact with hard surfaces frequently. When engaging in strenuous physical activities, the fat layer provides the body with extra padding. Other functions of lipids include hormones production, helping in digestion, and facilitating bioavailability.

Health Effects

Although lipids are important for healthy living and in supporting various body processes, excessive fats in the blood put individuals at risk of developing heart and liver diseases. Heart diseases have been found to be among the top ten causes of death in the US and other parts of the world (Gurr and Harwood 170). A buildup of LDL, for example, causes clogging of arteries that leads to stroke and other cardiovascular diseases. Excessive fat levels are associated with a high intake of foods such as cheese, fatty meat, cream, fried foods, butter, milk, and processed foods. To avoid excessive fats going directly to the bloodstream, HDL-promoting foods are recommended including olive oil, fish, legumes, vegetables, nuts, and fruits rich in fiber.

Lipids and their Importance

Lipids Nutrients are the chemicals that humans need to live and grow. Humans obtain their nutrients from the food and water that they drink. They are used to build and repair tissues and regulate body processes and are converted to and used as energy. Lipids are a category of nutrients. Lipids consist of fats, oils, and waxes and are very important for are body’s health. Lipids are important for the human body because they are for storing energy, they’re good at storing energy because they can concentrate a group of calories in a smaller area. There are many functions lipids have. One of the main functions lipids are structural components in the cell. Lipids make up approximately 50% of the mass of most cell membranes. The lipids that are found in the cell membrane are called phospholipid. Phospholipid are the predominant lipids of cell membrane. Phospholipids aggregate or self-assemble when mixed with water, but in a different manner than the soaps and detergents. Because of the two pendant alkyl chains in phospholipids and the unusual mixed charges in their head groups, micelle formation is unfavorable relative to a bilayer structure. Fatty acids are another type of lipid . The common feature of fatty acids is that they are all esters of moderate to long chain fatty acids. Two polyunsaturated fatty acids, linoleic and linoleic, are designated "essential" because their absence in the human diet has been associated with health problems, such as scaly skin, stunted growth and increased dehydration. These acids are also precursors to the prostaglandins, a family of physiologically potent lipids present in minute amounts in most body tissues.

Some of the remaining double bonds are isomerized in this operation. These saturated and trans- fatty acid glycerides in the diet have been linked to long-term health issues such as atherosclerosis. There are many more lipids than I have mentioned in my research paper, there are over a 100 know lipids. Lipids are very important for our body and cells and they carry out many function. They provide nutrients for our body. Lipids are a category of nutrients. Lipids consist of fats, oils, and waxes and are very important for are body’s health. Lipids are important for the human body because they are for storing energy, they’re good at storing energy because they can concentrate a group of calories in a smaller area. Lipids are also used to make soaps, detergents and waxes. These are things that we use in every day life.

Essay On The Beta Carotene Test Lab

To uncover organic compounds like carbohydrates, lipids, proteins and nucleic acid, by using tests like Benedict, Lugol, Biuret and Beta Carotene. Each test was used to determine the presents of different organic molecules in substances. The substances that were tested for in each unknown sample were sugars, starches, fats, and oils. Moreover, carbohydrates are divided into two categories, simple and complex sugars. Additionally, for nonreducing sugars, according to Stanley R. Benedict, the bond is broken only by high heat to make make the molecules have a free aldehydes (Benedict). As for Lipids, there are two categories saturated and unsaturated fats. One of the difference is that saturated fats are mostly solids and have no double bond (Campbell Biology 73). The Beta Carotene test works by dissolving in a lipid, thus giving it color to make it visible. Moreover, proteins are made out of amino acids that are linked by a polypeptide bond (Campbell Biology 75). The purpose of this experiment was to determine whether an unknown class sample or food sample had any carbohydrates, lipids, or proteins in it. The expected result of the lab was that some substances would be present while other would be absent.

Lipid metabolism is one source of energy for the human body. We eat food containing one form of lipids, triacylglycerols. Before starting lipid metyabolism, these fats get broken down into droplets by bile salts.Triacylglycerols can be broken into fatty acids plus glycerol via hydrolysis with the help of the pancreatic lipase enzymen and then get used by cells for energy by breaking down even further. Once the pancreas and cells have enough energy and don’t need to absorb anymore, fatty acids get synthesized back into triacylgleryols. The excess triacylglycerols get stored in adipose tissue. Excess storage leads to weight gain and obesity.

Many types of saturated fat are found in meat and dairy products. These fats are hard to break down for cells, because of this, they tend to get tucked away and build up over time if worked off. Unsaturated fats are found in olive oil and other plant oils. These types of fat are readily consumed for energy.

Nutrition Vs Nutrition

Food contains variety of nutrients, which is essential to our bodies. Nutrition is necessary to support the activities of day-to-day living. Nutrients in the food help maintaining normal growth and development, tissue maintenance and repair, cellular metabolism, and organ function (Potter, 2012, p.996). There are two groups of nutrients: macronutrients such as proteins, carbohydrates, fats, and micronutrients such as vitamins and minerals. However, nutrition should include water too because water helps protecting and repairing cells from environmental damage. Each nutrient has its own functions to restore our body. Proteins rebuild damaged tissue and promote growth. Carbohydrates and fats provide energy to the body, while vitamins and minerals function throughout the body in support of body’s processes. Water is essential for cellular homeostasis and life: it removes waste products including toxins out of vital organs. It moves nutrients to the cells, regulates body temperature, and providing a moist for brain, eyes, ears, nose, mouth, spinal cord, and

According to PosnerB.M (1998), he define essential nutrients as a nutrients that the body cannot synthesize on its own-or not to an adequate amount and must be provided by the died. Oxford dictionary (2009), also define essential nutrients as are those nutrients that are required by the body and cannot be synthesise in the adequate amount to meet requirement, so must be provided by the diet. Essential nutrients are those found to be essential to human life and optimal function, Williams.M. H (2006).There are six main type of nutrients used to maintain body health. They are carbohydrates, protein, fat, vitamins, minerals and water. They must be in balance for the body to function properly.
