Phosphatidylserine (PS) is a naturally occurring phospholipid that serves as a critical structural component of cell membranes, particularly concentrated in neural tissues.
It is a glycerophospholipid consisting of a glycerol backbone esterified to two fatty acids and a phosphoserine head group.
In mammals, PS is synthesized from phosphatidylethanolamine or phosphatidylcholine via base-exchange reactions.
PS plays an essential role in membrane fluidity, signal transduction, and cellular communication. It is particularly abundant in the cerebral cortex and hippocampus, where it supports neurotransmitter release, synaptic plasticity, and neuronal membrane integrity. Its role in cellular signaling includes activation of protein kinase C (PKC) and regulation of ion channels.
Phosphatidylserine supplementation has been extensively studied for its effects on cognitive function, stress response, and age-related cognitive decline. It is considered a well-established nootropic ingredient, supported by a substantial body of clinical research.
