Phosphatidylserine (abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane. It plays a key role in cell cycle signaling, specifically in relation to apoptosis. It is a key pathway for viruses to enter cells via apoptotic mimicry. Its exposure on the outer surface of a membrane marks the cell for destruction via apoptosis. Its main function is to improve the function of nerve cells, regulate the transmission of nerve pulses, and enhance brain memory function. Due to its strong lipophilicity, it can quickly enter the brain through the blood-brain barrier after absorption, playing a role in soothing vascular smooth muscle cells and increasing blood supply to the brain.
