Structure of fatty acids:
Differentiating between fatty acids can be in two main ways: the length of free fatty acid chains and the fatty acids degree of saturation. The number of carbon atoms determine the length of fatty acid chains which often categorized as short chain fatty acids (SCFA), Medium-chain fatty acids (MCFA), Long-chain fatty acids (LCFA), and Very long chain fatty acids (VLCFA) with aliphatic tails longer than 22 carbons, while the number of double bonds between carbon atoms determine their degree of saturation. Fats can be categorized into saturated fats and unsaturated fats. Furthermore, the unsaturated fats divide into monounsaturated fats and polyunsaturated fats. Fatty acid can be saturated if there are no double bonds

Unsaturation fatty acid chains with one double bond present is a monounsaturated fatty acid, but if it contains two or more double bonds in the carbon chain of a fatty acid it is a polyunsaturated. In the chain, the two carbon atoms, which are bound next to each side of the double bond, can occur in a cis or trans configuration (figure 2). Saturated fat tends to raise blood cholesterol levels. Unlike saturated fats, most unsaturated fats are good and tends to lower LDL cholesterol. However, the trans-fat is an exception of that because it is generally considered to be bad for the person's health. The temperature when the molecule melts affected by The degree of unsaturation of the fatty acids in a fat. Mostly, the more saturated a fat, the more solid and firmer its consistency, so largely saturated animal fats are solid. In contrast, it remains more liquid at room temperature if it more unsaturated a fat. Therefore, vegetable oils that containing monounsaturated or polyunsaturated fatty acids …show more content…
The main difference between the two is based on whether the body can produce them or not. Essential fatty acids must come from the diet or dietary supplements because they can not be synthesized by the body, while the body can produce non-essential fatty acids though they still can be ingested from the food. Basically, there are only two kinds known to be essential fatty acids for humans: alpha-linolenic acid, an omega-3 fatty acid, and linoleic acid, an omega-6 fatty acid. However, there is some other essential fatty acids categorized as conditionally essential which become essential under some disease or developmental conditions such as docosahexaenoic acid and gamma-linolenic acid. Age, gender and many factors impact the need for the omega acids and the rate in which they have to be consumed. Generally, the amount of omega 6 should to be lower than that of omega 3. The primer functions of the essential fatty acids are to maintain healthy cell membranes, help to produce hormone-like substances, help with the regulation of blood flow, and important for brain development and function. Good sources of omega-3 fatty acid are leafy green vegetables, fish and their oils and eggs when omega-6 fatty acid is found in meat and vegetable oils and processed foods that made with these

The purpose of this report is to explore the controversial dispute between the quality of two different forms of fish oil supplementation; Triglyceride (TG) and Ethyl Ester (EE). Fish oil can be implemented into a diet by eating either fish or taking supplements. Fish oil is extracted from selected fish that contain highly beneficial healthy oils known as omega-3 fatty acids, two of the most important omega-3 fatty acids that are found in fish oil are Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA). Some of these fish that contain healthy omega-3 fatty acids include Tuna, Salmon, Mackerel, Herring, Anchovy’s etc. Fish oil supplementation also often contains small amounts of vitamin E to prevent spoilage and is can be combined with various other minerals and vitamins. There is an array of benefits that are involved when implementing fish oil into a diet; although it’s most common association is that it has been linked to slightly lowering blood pressure or triglyceride levels (fats linked to cholesterol). Although fish oil is recommended for persons with high blood pressure, it’s extremely important to remember that it is only to be taken at recommended dosages as it can ironically increase the chances of stroke when overdosing on the supplement. The scope of this report includes a general comparison between TG and EE fish oil supplements and how they are chemically differentiated, with a focus on how the quality of the two forms of supplement are processed. This report will not focus on other forms of fish oil sources and the impact it might have on irreversible factors such as age, gender, genetics, race/culture or environmental conditions.

The Structure and Function of Carbohydrates Large biological molecules are called macromolecules, there are giant molecules (polymers) made up of repeating units (monomers). Carbohydrates are one of the main classes of biological molecules. Macromolecule units (monomers) are joined together by condensation reactions and hydrolysis reactions split macromolecules down into their individual units. Carbohydrates are molecules that contain elements of carbon, hydrogen, and oxygen. Carbohydrates have a 2:1 hydrogen to oxygen ratio, there are twice as many hydrogen atoms as oxygen atoms (the same proportion as in water).
The way metabolic syndrome is related to nutrition is because this condition can lead to strokes, heart attacks and more severe conditions that can lead to death if you do not take care of your body. Carbohydrate consumption has been a factor for weight gain, obesity, diabetes, and a number of other diseases. High-fiber diets are also factors that can lead to several metabolic disorders such as hypertension, diabetes, obesity, as well as heart disease and colon cancer. Fat is a general term used to refer to oils, and the consumption of unsaturated fats, derived mostly from vegetable oils such as safflower, corn, olive and soybean oil, may be able to prevent serious disorders, such as hypertension a...
Eating a lot of trans fats will dramatically increase the chances of getting heart disease. Aaron Carroll a professor of pediatrics at the indiana university school of medicine says “Trans fats are amazingly bad for you. By the 1990s, evidence was building that trans fats carried a significant risk for increasing coronary heart disease”
Omega-3 fatty acids are beneficial to everyone, whether they are still in the womb or 100 years old. The fatty acids are passed from mother to child via breast milk (as well as through internal fluids), a process which increases brain growth, serving as a building block for nerves and eyes in newborns and fet...

Overall trans fats are not a force to be reckoned with and have many repercussions to ignorant consumption. The unstudied and unrestrained early use of trans fats in food products have today’s society addicted to the taste-enhancing substance. Heart diseases, high cholesterol, obesity, strokes, heart attacks and diabetes are all linked to the over-consumption of trans fats. The negative repercussions on the American economy are a possibility but are not steep enough to stand by and watch the American public slowly waste away from the unrestrained consumption of this deadly killer.
Also, there are some products that vegans can take in enough amount of omega-3 fatty acids. In order to maximize production of DHA and EPA (omega-3 fatty acids), vegans should include good sources of alpha-linolenic acid in their diets such as flaxseed, flaxseed oil, canola oil, tofu, soybeans, and walnuts.
2) Fatty acids are made of a hydrocarbon tail and a polar carboxylic acid head. The carboxylic acid group has a charge of -1, therefore the molecule is negatively charged (which eliminates answers a, b, and e). For the fatty acid to become neutral, it has to be found in a low pH environment:
Another benefit of supplementing omega 3 into one’s diet is without adequate amount of omega 3 or if a deficiency of omega 3 exist, it can lead to a variety of serious side effects. This is because omega 3 is vital to many biological activities such as a role in the structure of the bodies cellular membranes, a role in the structure and function of the retina of the eye, and even a role in the function of the central nervous system. If an individual is lacking adequate amounts of omega 3(a deficiency of omega 3) it can result in impaired development of the retina or eye, impaired nervous system development including learning disabilities, growth retardation, and even though its though most mild side effect of an omega 3 deficiency, a dry scaly skin rash (Angelo, par8-10). In one particular case a deficiency of omega 3 was determined to be linked with a loss of visual ability, when the patient experiencing said loss of vision was supplemented intravenously with more ALA (Angelo, par. 20). One other pro or benefit of taking an omega 3 supplement, is typically the only side effects associated with taking an omega 3 supplement such as a fish oil capsules is minor gastrointestinal distress including indigestion or belching with a fishy taste in one’s mouth, due to the fact that the oil sits in your
Saturated fats come from animal sources like steak, hamburger and pork. Unsaturated fats are derived from plants. There are also trans fats that are considered poison for the body. They raise the bad cholesterol in your body, and should never be included in a healthy diet. There are also fatty acids like omega-3 and omega-6 that are good for a healthy body.
Lipids and triacylglycerol are naturally occurred compounds in oils and fats. The chemical composition contains saturated and unsaturated fatty acids and glycerides. Edible oils is an important component of our daily diet, that give energy, essential fatty acids and supply as a carrier of fat soluble vitamins For example, mustard oil had provided 30% of protein, calcium, phytins, phenolics and natural anti-oxidants. Besides, mustard oil has a high sum of mono-unsaturated fatty acids and a good ratio of polyunsaturated fatty acids, which is good for the heart (Zahir et al.,
