To create an effective lower-body workout routine, start with your biggest muscle groups. I agree with what Dr Hasan said, because the synthesis of enzymes in the form of zymogens is one of the "safety mechanisms" that the body has for its survival. Zymogens of Proteolytic Enzymes. Zymogens, rather than active enzymes, are typically secreted by the human body, because they can be stored and transported safely without harms to surrounding tissues, and released when conditions are favorable for optimal activity. Advice that fits in with busy lives. Digestive enzymes are made as zymogens and are stored in zymogen granules. 1. any of a group of compounds that are inactive precursors of enzymes and require some change (such as the hydrolysis of a fragment that masks an active enzyme) to become active Familiarity information: ZYMOGEN used as a noun is very rare.
