c) Phospholipases hydrolyse the specific ester
bonds that connect the different building blocks which makes up a
phospholipid molecule.
Phospholipases are group of enzymes either calcium dependent or
calcium independent. These enzymes hydrolyze the phospholipids to
fatty acids; play an important role in maintaining the membrane
integrity, cell signaling functions. There are four major types of
phospholipase enzymes which is differentiated based on the type of
reaction they catalyze such as phospholipase A that hydrolyse acyl
ester bonds at both phospholipase A1(sn1) and phospholipase A2
(sn2) position. Phospholipase B again cleaves sn1 and sn2 of acyl
chains. Type C cleaves glycerophosphate bond and type D cleaves
after the phosphate releasing phosphatidic acid and an alcohol.
Therefore phospholipases are key players to maintain the health
condition.
