• phospholipase is an enzyme which has activity towards phospholipids.
• Phospholipids such as lecithin or phosphatidylcholine, consist of glycerol esterified with two fatty acids in an outer (sn-1 ) and the middle (sn-2) positions and esterified with phosphoric acid in the third position; the phosphoric acid, in turn, may be esterified to an amino-alcohol.
• Phospholipases are enzymes which participate in the hydrolysis of phospholipids.
• phospholipases Ai and A2 which hydrolyze one fatty acyl group (in the sn-1 and sn-2 position, respectively) to form lysophospholipid
• lysophospholipase or phospholipase B which can hydrolyze the remaining fatty acyl group in lysophospholipid.
• Phospholipase C and phospholipase D release diacyl glycerol or phosphatidic acid respectively.
• proteases hydrolyse bonds within peptides and proteins, in the laundry context this leads to enhanced removal of protein or peptide containing stains.
