There exist many books on enzyme kinetics that offer thorough, in-depth treatises of the subject. This book stresses understanding and practicality, and is not meant to .

As the enzyme alters its shape, the enzyme puts strain on the substrate molecule and thereby lowers its activation energy, this process is known as the induced fit theory of enzyme action. Lipase is a type of enzyme known as a hydrolase and is responsible for catalysing the hydrolysis of tri

The Role of Enzyme Supplementation in Digestive Disorders. Abstract This article reviews various forms of enzyme supplementation . used clinically in digestive and absorption disorders. Enzyme supplementation plays an integral role in the management of various digestive disorders, particularly with regard to exocrine pancreatic insufficiency.

The enzyme is free to repeat this process, catalyzing the reaction over and over again until it is no longer active. Like any protein, the action of an enzyme is dependent upon its unique three-dimensional shape. Anything that causes an enzyme to adopt a non-functional shape is said to denature the enzyme.
