| + | **WHY PROTEOLYTIC ENZYMES RELEASED IN ZYMOGEN FORM??** | ||
| + | * Several proteolytic enzymes found in the blood or in the digestive tract are present in an inactive (precursor) form, called zymogen or proenzymes. | ||
| + | * For example, chymotrypsin is secreted by the pancreas as chymotrypsinogen. It is activated in the digestive tract by the proteolytic enzyme trypsin. | ||
| + | * Zymogens are also associated with blood clotting, formation of insulin, formation of collagen and apoptosis. | ||

| + | * Proteolytic enzymes are released in zymogen form to prevent them from prematurely digesting proteins within the cells where they are synthesized. | ||
| + | * This helps to avoid damage to cellular structures and ensures that digestion only occurs where and when it’s needed. | ||
| + | * This inactive form acts as a safety mechanism until the enzyme reaches its target site, where it’s activated by specific cleavage events. | ||
| + | * Process of cleavage : Activation of zymogen usually occurs through cleavage of a specific peptide bond, triggered by other enzymes | ||
