Model 34800 - Phosphatidylcholine

Phosphatidylcholine is the most abundant phospholipid in mammalian, plant, and yeast cells.1 It is found mainly in the outer leaflet of cell membranes and can make up approximately half of the total phospholipids.2 In mammalian tissues, phosphatidylcholine commonly contains a saturated and unsaturated fatty acid at the C-1 and C-2 positions of glycerol, respectively. It is a substrate for various enzymes in cell signaling pathways that is cleaved by phospholipases into diacylglycerol and phosphocholine or phosphatidic acid and choline. This product contains phosphatidylcholine molecular species with variable fatty acyl chain lengths at the sn-1 and sn-2 positions.
