一般描述
Phosphatidylcholine (PC) (Lecithins) has two fatty acid chains attached to a head group. Generally, PC has saturated fatty acid in thesn-1 position and unsaturated fatty acid in thesn-2 position. It has a quaternary ammonium group and a phosphate moiety in the head group, existing as a zwitterion in a wide range of pH. The fatty acid in PC is mostly palmitic, stearic, oleic, linolenic and arachidonic acid. It is present abundantly in the mammalian membranes. PC is principally synthesized from cytidine diphosphate-choline (CDP-choline). Selective deuteration of this lipid may be used in the structural studies using techniques such as nuclear magnetic resonance (NMR), neutron reflectivity and small-angle neutron scattering.
生化/生理作用
Phosphatidylcholine (PC) is essential for cholesterol trafficking and membrane cholesterol homeostasis. It acts as the precursor for the synthesis of sphingomyelin. PC plays a key role in the synthesis of second messenger and signaling molecules like diacyl glycerol, lysophosphatidic acid, phosphatidic acid and arachidonic acid.
