Phospholipase A2 (PLA2, EC cleaves the sn-2 fatty acid of phospholipids, primarily phosphatidylcholine, to generate lysophosphatidylcholine and arachidonic acid. Most commonly-used inhibitors (e.g. bromoenol lactone, arachidonyl trifluoromethyl ketone or methyl arachidonyl fluorophosphonate) are either non-selective within the family of phospholipase A2 enzymes or have activity against other eicosanoid-metabolising enzymes.

Secreted or extracellular forms: sPLA2-1B, sPLA2-2A, sPLA2-2D, sPLA2-2E, sPLA2-2F, sPLA2-3, sPLA2-10 and sPLA2-12A

Cytosolic, calcium-dependent forms: cPLA2-4A, cPLA2-4B, cPLA2-4C, cPLA2-4D, cPLA2-4E and cPLA2-4F

Other forms: PLA2-G5, iPLA2-G6, PLA2-G7 and PAFAH2 (platelet-activating factor acetylhydrolase 2)
