omega3

We call substances which are hydrophobic and greasy, fats. The definition, used in chemistry, is different. Only triglycerides, which are esters of organic acids formed with glycerol, are called fats. Some of those substances we call oil are also triglycerides. Fats are simple lipids. They are biologically important natural compounds produced by plants and animals. Saturated Fatty Acids Saturated fatty acids (such as palmitic acid) have no double bonds or other functional groups except for the carboxyl group. The straight chains pack tightly, which makes it possible for living creatures (especially for animals) to store energy in high amount in a relatively small space in the form of fat. Unsaturated Fatty Acids There is at least one double bond within the chain of unsaturated fatty acids. Depending on the position of hydrogen atoms in the double bond, they may be either cis- or trans- fatty acids. Essential Fatty Acids Essential fatty acids are polyunsaturated compounds which include omega-6 fatty acid (linoleic acid) and omega-3 fatty acid (alpha-linolenic acid, ALA). These are essential nutrients, because the body cannot produce them. Essential fatty acids play an important role in reducing inflammation, regulating blood pressure, and in the proper function of the immune ...
