WebLipases. C.T. Hou, Y. Shimada, in Encyclopedia of Microbiology (Third Edition), 2009. Lipases (triacylglycerol hydrolases E.C. 3.1.1.3) are enzymes that catalyze the hydrolysis of triacylglycerols (TAGs) to glycerol and fatty acids (FAs). Lipases, together with amylases and proteases, constitute the three major known digestive enzymes. sharpen pdf adobe
