what is the difference between rennin and renin?
Rennin also called as chymosin is an enzyme (act similarly as pepsin) which is synthesized by chief cells (gastric mucosa) of stomach in some ruminant animals like calves. It is required for digestion of milk.
Renin is a enzyme produced by human kidneys that participates in the body’s renin-angiotensin-aldosterone system (RAAS), a hormone system that regulates blood pressure and fluid balance. It acts on angiotensinogen (a protein) and cleaves to produce angiotensin I (a decapeptide) which regulated arterial blood pressure.
