Glycerophospholipids act as regulators of various enzyme activities, and can be used as biological markers to indicate pathological states.
Biological Activity
Phosphatidic acid (PA) is a bioactive lipid and acts as a secondary messenger. It is associated with hydrogen peroxide production in the neutrophils. PA stimulates the action of protein kinase for neutrophil respiratory burst. It also participates in Ras mediated signaling pathways. PA reacts with water and other phospholipids to produce lipid bilayers and multicomponent bilayers respectively.
