What are saturated fat; three examples of saturated fats
These are fat that is made up of atoms that are very dense and the hydrogen atoms fully join with carbon atoms with no double bonds. This makes the carbon atoms in the fat’s molecular structure to be fully saturated with hydrogen atoms. Three examples of saturated fats are; 1) Butyric acid - milk (especially buffalo, goat, and sheep), butter, Parmesan cheese. 2)Lauric acid - coconut oil, palm kernel oil, laurel oil. 3) Myristic acid - nutmeg, coconut oil, palm kernel oil and butterfat.

What are unsaturated fats; three examples of saturated fats:-
Unsaturated fat is a fatty acid that has one or more double bonds. These double bonds eliminates hydrogen atom from the molecular fatty acid chain. This makes unsaturated fats unsaturated with hydrogen atoms. Three examples of unsaturated fats includes: - walnuts, olive oil and cashew nuts. (Wikipedia,2015)

Trans fat are more commonly man made from vegetable oil. The vegetable oil are heated or hydrogenated to create the trans fat. Three examples of foods that use trans fat are margarine, biscuit and frozen pizza. (Wikipedia,2015)
Why might food producers add hydrogen atoms to a vegetable oil
They would do this because vegetable oils are unsaturated with hydrogen atoms; by adding hydrogen atoms to the vegetable oil; it will make the liquid vegetable oils into solid or semi solid fats. This will make the vegetable oil fat more dense and thus make it more desirable for use in baking. The dense properties are more desirable for use in baking because of the more wanted texture vs the texture that would be made with the natural unsaturated vegetable oils. (wikipedia, 2015)
Is there a downside to the hydrogenation
One reason is that it can prevent obesity. In “should the government regulate what we eat and drink” Bert Glass explains how “advocates that support the ban on trans fat are quick to point out the negative health effects of consuming food prepared with the banned item. He also states that, “trans fats can raise our level of “bad” cholesterol while also lowering our “good” cholesterol levels, both of which contribute to heart disease. In the text Bert gives an example of what trans fat can do and how it can affect our body. He also talks about how trans fat can contribute to heart disease which is a disease nobody wants to get.
Unsaturated fatty acid not filled with all the hydrogen it can hold. Because of that, it's less thick and less dense like liquid oil. Monounsaturated fat has one empty spot. Examples of monounsaturated fat include plants base liquid oil which contains olive oil and peanut oil
(b.) The fluidity of lipids depends on the length and saturation of their hydrocarbon tails. Butter is a saturated lipid with a short hydrocarbon tail, waxes are lipids with extremely long hydrocarbon tails but are still saturated, and oils are unsaturated lipids with long hydrocarbon tails.
Saturated fats were said to be linked to health risks that are detrimental to society as a whole. These health risks include the development of heart disease and type II diabetes
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
The process of creating trans fat originated from the 1890s in France when chemist Paul Sabatier discovered that metal catalysts could precipitate hydrogenic reactions. This led to German chemist Wilhelm Normanns’ 1901 experimentation with hydrogenation catalysts that successfully led to the hydrogenation of liquid fat which produced semi solid fat that is now known as trans-fat. This process was adopted by many food manufacturers because of its ability to stabilize the shelf life of products it is in. With the production and use of trans fat comes some serious health risks. In the 1950s it was found that there is a clear connection between the intake of saturated fats and heart disease. After this was found there was some opposing studies that proved fats were healthy. By the 1980s it was established that a high intake of saturated fat led to a higher risk for heart problems. Because of this trans fats were used to replace saturated fats, but it was later found that trans fat held a higher risk for heart problems than saturated fats did (“Trans Fat”). Once people discovered this, a demand for healthy alternatives began and is still prevalent today.
Unsaturated fatty acids are characterized with having at least one carbon double bonded with another carbon, losing the normal bond with hydrogen and the corresponding hydrogen. The number of double bonds, hydrogens, and carbons differ in structure of different types of fatty acids and cause the difference in function between the fatty acids. But even though most fatty acids are different from each other due to structure and function, all unsaturated fatty acids do have some things in common. They all enter the cell via the membrane and increase the fluidity of the plasma membrane, increasing overall cell health, and they all form unsaturated fats [3]. Unsaturated fats are made up of many different strands of different types of fatty acid. The type of unsaturated fatty acid I will be talking about today is an omega-3 fatty acid made up of three different types of fatty
In the early 1900s, dietary fat was viewed simply as a source of calories, interchangeable with carbohydrates. But in 1929 and 1930, George and Mildred Burr discovered that fatty acids were critical to health through punctilious analyses of rats fed special diets. If fatty acids were missing in the diet, a deficiency syndrome ensued and often led to death (Asbmb.org. 2016). Fatty acids rarely occur as free molecules in nature but are usually found as components of many complex lipid molecules such as fats and phospholipids. Biological fatty acids are composed only of hydrocarbon chain which is carbon, hydrogen and oxygen in the proportion of 76%, 12.6% and 11.3% respectively with one terminal carboxyl group (COOH). Fatty acids are aliphatic
Also it is important on where the fat is carried on the body that contribe to health problems. Belly fat for example is stored deep below the skin, causing it to be surrounded by the organs and liver. Saturated and trans fats are big ones to try and avoid. These types of fats are known to increase the risk of diseses and high cholesterol. Foods that include Saturated fats tend to be, cuts of meat like beef and pork, chicken but with the skin, whole-fat dairy products, butter, cheese, palm/coconut oil and many more. Trans fat foods include things like, baked goods, margarine, fried foods, potato chips, etc. Knowing the type of "bad fat" to look out for is important, but so is knowing what the "good fats" are. Monounsturated fats are found in olive/canola/sunflower/peanut/sesame oils, Avocados, olives and nuts. There is also Polyunsaturated fats that include, Soybean/corn/safflower oils, walnuts, Seeds such as sunflower, sesame, pumpkin and flaxseeds, fatty fish like salmon and tuna, soymilk and tofu. These types of fats have heath benifits because they are good for the heart and also cholesterol. Fats disgest differently than the other molecules dessuted earlier, because the fat does not dissolve into the the disgestive juices. Bile which is produced by the liver but is stored in the gallbladder, are able to attach to the fat molcules and break it up into smaller particles, but lipase which is a fat-disgesting enzyme can break it down. It gets broke down into fatty acids and chlesterol which are then absorbed through the intestinal wall to the bloodstream. The fat is then stored in the body to be used as energy when it is
In recent years, experts in the health and wellness community have debunked the old line of thinking that fats are hazardous to health. With this news, one type of fat has been recognized as being most essential to human health: omega-3 fatty acids. These good-for-you fats provide an abundance of health benefits, but the body cannot make them.
There are many trans fats in the foods that seem healthy that is why people should watch what they eat and take care of their bodies as much as they can. One might not know this, but trans fats are formed when oils that are liquid at room temperature are mixed with hydrogen and become solid fats. People will not be able to notice when they are consuming these trans fats because they have a taste and texture that many consumers find desirable. Trans fats can raise our level of “bad” cholesterol while also lowering our “good” cholesterol levels which can contribute to heart disease. These can also lead to a numerous amount of health problems requiring medical
The body needs fat to function, they serve many different purposes. Fifty percent of the cell wall is made up of saturated fat.(Stevenson) Trans fats are bad for several reasons. First of all, a saturated fat molecule compared to a unsaturated fat molecule that is a trans fat, have the same chemical makeup, and this is a major problem with the way the body uses trans fats. Because they are so similar, trans fats can take the place of saturated fats in the cell wall. Cell walls are porous, they take in nutrients and expel waste or toxins. When trans fats take the place of saturated fats in the cell wall, because of the placement of the double bonds on the polar ends, this makes the molecule not want to cooperate with other molecules. This leads to gaps in the cell wall which allow toxins to penetrate into the cell. Another problem that happens when trans fat molecules replace saturated fat molecules is typical cell communication is disrupted, this can cause nutrients to not be taken into the cell and toxins to be trapped inside the cell, and can lead to an unbalanced metabolism. Abnormal cell communication also effects hormone signals and reflexes, which can instigate the body to overproduce adrenaline, and in turn lead to adrenal fatigue and even a non-functioning thyroid. (Benson) Trans fats have a very negative effect on the cardiovascular system as well. This type of fat increases the production of LDL cholesterol and triglycerides which clog and cause the narrowing of the arteries, and they lower HDL cholesterol, the good cholesterol. Also, in addition to all the adverse effects trans fat have on the body, they are difficult to digest and in turn they cause inflammation. Inflammation can wreak havoc on the body and cause multiple diseases. (“Dietician to
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
My saturated fats were labeled as “ok”, so I ate the recommended amount. Trans fats are fats that were hydrogenated so the product can last longer. It's found in things like margarine, cakes, fries, etc. It is recommended to eat as little amount of saturated fats as possible because they cause heart disease.
