Answer:
ADA is an enzyme that is used to breakdown the food chain.
Explanation:
ADA is also called adenosine deaminase. It is an enzyme. It is a purine metabolism. ADA is used to needed for the breakdown of the adenosine from the food chain. ADA is found in both small and large form. The enzyme presented in it has polypeptide chain. It is folded in eight strands.
The ADA contain zinc. It is found in deepest site and combined with five form such as 15, 17, 214, 295 and the substrate.
The ADA is is inversible dominates the adenosine. It is considered the key enzyme of the purine metabolism. ADA in human beings work for development and maintenance.
