However, the majority of fatty acid biosynthesis occurs in hepatocytes and adipocytes. In fig. biochemistry and physiology open access open access journals. Phosphatidic acid is chemically the parent of the glycerophosphatides, and the relationship between this compoundand Phospholipids are a class of lipids that consist of two fatty acyl molecules esterified at the sn-1 and sn-2 positions of glycerol, and contain a head group linked by a phosphate residue at the sn-3 position. [10] • The phosphatidic acid itself may be formed from glycerol-3-phosphate or DHAP. This release may happen along several possible metabolic routes (Figure 12.2a). From Wikimedia Commons, the free media repository. In all tissues except liver, phospholipids are synthesized, utilised and degraded in situ; while in liver large proportion of the phospholipids after synthesis is transferred to the plasma and as a matter of fact, liver is practically the sole source of plasma phospholipids. Biosynthesis. Phospholipids and glycolipids consist of two long, ... Only small amounts of phosphatidate are present in membranes. 1, the structural relation-ships between glycerol, diglyceride, and phos-phatidic acid are shown.
