The biosynthesis of fatty acids requires NADPH which is mainly provided by the oxidation of glucose in the pentose-phosphates cycle. Digestion is the first step to lipid metabolism, and it is the process of breaking the triglycerides down into smaller monoglyceride units with the help of lipase enzymes. Chapter 8 Lecture Notes Lipids 1 Chapter 8 Lecture Notes: Lipids Educational Goals 1. The biosynthesis of triglycerides in most tissues is generally considered to occur primarily via the sn-glycerol-3-phosphate pathway.In tissues known to carry out the synthesis of triglycerides, the activity of the glycerol-3-phosphate pathway is relatively constant (Schultz and Johnston, 1971). unit iv: nitrogen metabolism.

You can change your ad preferences anytime. Chapter 5 The Lipids: - . Acetyl-CoA in fat synthesis temporarily bound to enzyme complex as malonyl-CoA. Most of the fatty acids synthesized or ingested by an organism have one of two fates: incorporation into triacylglycerols for the storage of metabolic energy or incorporation into the phospholipid components of membranes. ap biology unit 2. flow of genetic information. Lipid digestion. Glucose, Glycerol, & Fatty acids all supplyacetyl CoA to be oxidized in the Krebs cycle. Digestion of fats begin in the mouth through chemical digestion by lingual lipase.Ingested cholesterol is not broken down by the lipases and stays intact until it enters the epithelium cells of small intestine. Triglycerides form by condensation (dehydration) reactions between the hydroxyl (OH) groups of the glycerol and the carboxyl (COOH) group of three fatty acids. Synthesis of Triglycerides The major building block for the synthesis of triacylglycerols, in tissues other than adipose tissue, is glycerol-3-phosphate. What about adipose tissue? FAS is a large multienzyme complex. Cholesterol synthesis: • Cholesterol used in every cell membrane • Precursor for: • Bile salts • Vitamin D • Adrenal hormones: • Glucocorticoids • Mineralocorticoids • Sex hormones: • Estrogens (female) • Progestins (pregnancy) • Androgens (male). 1805 – cuvier makes the difference between adrenal cortex and medulla. The constitution of different species of saturated and unsaturated fatty acids at the sn-1, sn-2, and sn-3 positions of the glycerol backbone varies among different plants, and is determined by substrate specificities of the three acyltransferases involved in this pathway.
