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. Web7 jul. 2024 · Advertisement. When an enzyme is saturated with substrate it means the substrate concentration reaches a point at which none of the available active sites are free. Since the reaction rate is now determined by how fast the enzyme-substrate complex is converted to product, the reaction rate becomes constant- the enzyme is saturated. WebAt this specific pH level, a particular enzyme catalyzes the reaction at the fastest rate than at any other pH level. For example, the enzyme pepsin … dynamic 3 trial
