General description

Phosphoserine/phosphatidylserine (PS) is an endogenous phospholipid, that is found in all polyanionic macromolecules. 1,2-dioleoyl-sn-glycero-3-phospho-L-serine (DOPS) carry a carboxylic acid group and a protonated amine group in their head group.
DOPS is an excellent substitute for the naturally occurring Brain PS. It has similar physical properties and is more stable to oxidation. DOPS has been used, along with DOPC and DOPE, in lipid mixtures to mimic platelet membranes for coagulation studies.


18:1 PS (DOPS) has been used as a component of supported membrane tubes (SMrT) templates. It has also been used in the preparation of lipid-mixing vesicles, content-mixing vesicles and lipid mixture.

Biochem/physiol Actions

Phosphoserine (PS) can be used as a template for the recognition of cancer antigen 125 (CA 125). It is very essential for healthy nerve cell membranes and myelin. Exogenous PS can be actively absorbed in humans. It plays a key role in the formation of short-term memory, the consolidation of long-term memory, the ability to create new memories and several other cognitive activities. It actively participates in the locomotor functions, like rapid reactions and reflexes.
