Lipogenesis: Glucose conversion to Fatty Acids (REMEMBER, THE OPPOSITE DOES NOT HAPPEN) B. Hormonal and dietary factors. Perhaps Doinikow 1 and del Rio Hortega 2 were the chief advocates of the theory that myelin was a product of the activity of Schwann cells in the peripheral nervous system and of oligodendroglia cells within the central nervous system. The concept that Schwann and glial cells are related causally to myelin formation evolved slowly, and not without controversy. Dr. Ifat Ara Begum Assistant Professor Dept of Biochemistry Dhaka Medical College 2. This synthase complex have 7 enzymatic site on it and one ACP (acylcamer protein) site. The active one is the dimeric and is arranged in head to tail form. Overview of Lipid Metabolism: The major aspects of lipid metabolism are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis.Lipid metabolism is closely connected to the metabolism of carbohydrates which may be converted to fats. Organic acid containing a long hydrophobic hydrocarbon chain and a terminal carboxyl group. Fatty acid synthase complex is a multi-enzyme complex which have different catalytic reaction site on it. Lipogenesis is a metabolic process in animals that converts simple sugars to fatty acids and synthesizes triacylglycerols through the reaction of fatty acids with glycerol. The activity of acetyl-CoA carboxylase depends on its phosphorylation … They exist free in the body as well as fatty acyl esters in more complex molecules such as triglycerides or phospholipids. Reactions: Glucose to acetyl Coa to FA (see figure) **In ruminants, acetate, not glucose, in starting material for lipogenesis** The rapid increase in metabolic diseases, which occurred in the last three decades in both industrialized and developing countries, has been related to the rise in sugar-added foods and sweetened beverages consumption. Glycolysis, formation of acetyl CoA, Krebs cycle and the electron transport chain are all involved in: A) Lipogensis B) Gluconeogenesis C) Glucose catabolism D) Formation of Glycogen E) Formation of vitamin C 2. Pathway for De novo synthesis Regulation of lipogenesis. Lipogenesis 1. Lipogenesis is the process involving the synthesis of fatty acids or triglycerides, which is controlled and regulated by a number of factors in the body. The triglycerides in fat are packaged within cytoplasmic lipid droplets. Lipogenesis: the pathway of fatty acid synthesis The key regulating enzyme of lipogenesis is acetyl-CoA carboxylase, which catalyzes the synthesis of malonyl-CoA from acetyl-CoA and CO 2 . Lipogenesis is the metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. the formation of fat; the transformation of nonfat food materials into body fat. An emerging topic in the pathogenesis of metabolic diseases related to modern nutrition is the role of Advanced Glycation Endproducts (AGEs). After lipogenesis, the triacylglycerols are packaged into very low-density lipoprotein (VLDL) and secreted by the liver, and they help transport lipids and cholesterol throughout the body. In biochemistry|lang=en terms the difference between lipogenesis and adipogenesis is that lipogenesis is (biochemistry) the biochemical production of fat, especially the conversion of carbohydrate into fat so that it may be stored as a long-term source of energy when food is scarce while adipogenesis is (biochemistry) the formation of fatty tissue; lipogenesis. 11. adj., adj lipogenet´ic.
