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. Web11 apr. 2024 · Again, the shape of the enzyme, along with its active site, will change. Extremes of pH also denature enzymes. The changes are usually, though not always, permanent.

WebEnzymes can be deactivated by a range of factors. Often, this happens because of changes in temperature or pH. Enzymes are picky. Each enzyme has a small range of temperatures and pH levels at which it works best. We call this optimum pH and optimum temperature. If either one falls out of range, the enzyme works much less efficiently.
