General description

Phosphatidylserine(PS) is the major anionic phospholipid in human plasma and intracellular membranes identified first in brain. It is a structural component of endoplasmic reticulum, nuclear envelopes, Golgi apparatus, inner layer of plasma membranes, outer mitochondrial membranes and myelin.

Biochem/physiol Actions

Phosphatidylserine(PS) mediates the activation of enzymes and structural components. PS plays a key role in apoptosis by regulating cell signalling molecules and in monitoring membrane fluidity.
