Trans fatty acids are unsaturated fatty acids that contain at least one double bond in the trans configuration. Fats provide energy, insulation, and storage of fatty acids for many organisms.Chemical structure. 108 Trans fat contents in various natural and traditionally processed foods, in g per 100 g 109 Research suggests a correlation between diets high in trans fats and diseases like atherosclerosis and coronary heart disease.CLA has two double bonds, one in the cis configuration and one in trans, which makes it simultaneously a cis- and a trans-fatty acid. A trans fatty acid (commonly shortened to trans fat) is an unsaturated fatty acid molecule that contains a trans double bond between carbon atoms, which makes the molecule kinked.Omega-3 fatty acid and omega-6 fatty acid are essential for human biological processes, but they must be ingested in the diet because they cannot be synthesized. Olive oil, a monounsaturated fat, has a single double bond whereas canola oil, a polyunsaturated fat, has more than one double bond. Unsaturated fats may be cis (hydrogens in same plane) or trans (hydrogens in two different planes). Fats may be saturated (having single bonds) or unsaturated (having double bonds).carboxylA univalent functional group consisting of a carbonyl and a hydroxyl functional group (-CO.OH) characteristic of carboxylic acids.Fats have important functions, and many vitamins are fat soluble. It contains the functional group carbon-oxygen double bond joined via carbon to another oxygen atom. esterCompound most often formed by the condensation of an alcohol and an acid, by removing water.
![]() Unsaturated Fatty AcidsFatty acids may be saturated or unsaturated. Three molecules of water are released in the process. TriacylglycerolsTriacylglycerol is formed by the joining of three fatty acids to a glycerol backbone in a dehydration reaction. Putty x11Most unsaturated fats are liquid at room temperature and are called oils. Oleic acid is an example of an unsaturated fatty acid. Stearic acid and palmitic acid, which are commonly found in meat, are examples of saturated fats.When the hydrocarbon chain contains a double bond, the fatty acid is said to be unsaturated. Saturated fatty acids are saturated with hydrogen since single bonds increase the number of hydrogens on each carbon. Bandicam crack mediafireThe cis double bond causes a bend or a “kink” that prevents the fatty acids from packing tightly, keeping them liquid at room temperature. If hydrogens are present in the same plane, it is referred to as a cis fat if the hydrogen atoms are on two different planes, it is referred to as a trans fat. Cis and trans indicate the configuration of the molecule around the double bond. Unsaturated fats help to lower blood cholesterol levels whereas saturated fats contribute to plaque formation in the arteries.Unsaturated fats or oils are usually of plant origin and contain cis unsaturated fatty acids. If there is more than one double bond, then it is known as a polyunsaturated fat e.g. Many fast food restaurants have recently banned the use of trans fats, and food labels are required to display the trans fat content. Recent studies have shown that an increase in trans fats in the human diet may lead to an increase in levels of low-density lipoproteins (LDL), or “bad” cholesterol, which in turn may lead to plaque deposition in the arteries, resulting in heart disease. During this hydrogenation process, gas is bubbled through oils to solidify them, and the double bonds of the cis-conformation in the hydrocarbon chain may be converted to double bonds in the trans-conformation.Margarine, some types of peanut butter, and shortening are examples of artificially-hydrogenated trans fats. Trans FatsIn the food industry, oils are artificially hydrogenated to make them semi-solid and of a consistency desirable for many processed food products. ![]() Each singly bonded carbon has two hydrogens associated with it, also not shown. For clarity, the carbons are not shown. It has three cis double bonds and, as a result, a curved shape. Omega Fatty AcidsAlpha-linolenic acid is an example of an omega-3 fatty acid.
