The enzyme galactolipase (EC 3.1.1.26) catalyzes the reaction

1,2-diacyl-3-β-D-galactosyl-sn-glycerol + 2 H₂O

\rightleftharpoons

3-β-D-galactosyl-sn-glycerol + 2 carboxylates

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is 1,2-diacyl-3-β-D-galactosyl-sn-glycerol acylhydrolase. Other names in common use include galactolipid lipase, polygalactolipase, and galactolipid acylhydrolase. This enzyme participates in glycerolipid metabolism.
