The role of fatty acids yet no important and varied, particularly with respect to the Organization of the brain, heart, liver, gonads. Moreover, the study also found that the body can convert glucid and protein into the fatty acid no, but not the synthesis of fatty acids yet no that are available only through the food as linoleic, linolenic and arachidonic. People often rely on the nutritional value of fat to choose the fat in foods: the fatty acid content of not no need (b. a.), vitamins (Vitamin A, D and E), the phosphatid (lecithin), sterols (especially cytosterin), easy to digest and sensory properties. In fact, no fat would meet the full criteria, such as animal fats rich in vitamin A, vitamin D, but poverty on the fatty acids yet no vegetable oil, by contrast, have more linoleic acid, tocopherol, phosphatid and cytosterol but not the vitamins A and d. so use to coordinate animal fats and vegetable oils will create a balance and full of fat have high biological value. The ability to absorb and assimilate the fat is also an important point to note when choosing fats. Lipase enzymes involved are triglycerides hydrolysis produces the fatty acids and glycerol, the stomach and the small intestine make emulsion process and resolution, with the participation of the men, cut the fatty acid into the molecule has a small structure to absorb into the bloodstream and part is used as an energy source , a part is taken to the fatty tissue to reserve, to cells, to replace the fatty acids of cell membrane.
