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The enzyme is free to repeat this process, catalyzing the reaction over and over again until it is no longer active.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.
