Impact Factor Of Lipid Metabolism

 Lipid metabolism is that the synthesis and degradation of lipids in cells, involving the breakdown or storage of fats for energy and therefore the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. These fats are derived from food in animals, or are synthesized from the liver. Lipogenesis is the synthesizing process of those fats. Triglycerides and cholesterol are the bulk of the lipids present in the human body from consumption of food.Other sorts of lipids found within the body are fatty acids and membrane lipids. Lipid metabolism is often considered as the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy, from consumed dietary fats and from stored fat. Vertebrates use both sources of fat to produce energy for organs such as the heart to function. Since lipids are hydrophobic molecules, they need to be solubilized before their metabolism can begin. Lipid metabolism often begins with hydrolysis, which occurs with the help of various enzymes in the digestive system. Lipid metabolism also occurs in plants, though the processes differ in some ways in comparison to animals. The second stage following the hydrolysis is the incorporation of the fatty acids into the intestinal wall epithelial cells. Fatty acids are stored in the epithelial cells, and transported to the rest of the body.
