Abstract. Phospholipids have shown health benefits such as reducing blood cholesterol and triglycerides (Knuiman and others 1989), liver detoxification and repair of damaged liver tissue (Lieber and others 1990), improvement of cognitive functions (Pepeu and others 1996), and visual acuity (Koletzko and others 1995). stream • Phospholipids are synthesized from phosphatidic acid & 1,2-diacylglycerol, intermediates in the production of triacylglycerols. This paper will describe the enzymatic synthesis of cytidine diphosphate choline and cytidine diphosphate ethanol- amine, the isolation of these compounds from liver and yeast, and their function in the biosynthesis of lecithin and phosphatidylethanolamine.

The first step in the biosynthesis involves the oxidative cleavage of the sidechain of cholesterol by CYP11A, a mitochondrial cytochrome P450 oxidase with the loss of six carbon atoms to give pregnenolone. Microdetermination of Phospholipids. Phospholipids are secreted into the bile to aid in the digestion and absorption of dietary fat. Three conserved mitochondrial dynamin-related GTPases (i.e., mitofusin, Opa1 and Drp1 in mammals and Fzo1, Mgm1 and Dnm1 in yeast) mediate mitochondrial fusion and division.
