Glycerophospholipids act as regulators of various enzyme activities, and can be used as biological markers to indicate pathological states.
Phosphatidic acid (PA) is a diacyl-glycerophospholipid. With the help of ester linkage, two fatty acids and a phosphate group are attached to a glycerol molecule through covalent bonds. PA is rich in soy lecithin. It can be produced through phosphorylation of diacyl glycerol (DAG) with the help of diacylglycerol kinases (DGKs).
Phosphatidic acid (PA) is present in biomembranes. It is the precursor for other phospholipids and acts as a signaling molecule. PA is implicated in nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) activity. 10:0 PA along with 1-oleoyl-2-acetoyl-sn-glycerol (OAG) and arachidonic acid (AA) can be used as cell-free activators to promote NADPH oxidase activity.
