Distinguish between renin and rennin.
Explanation
Solution
The rennin is an enzyme whereas renin is a hormone which is produced by the gastric gland.Renin is the hormone that is produced by Kidney.
Complete answer:
| Rennin | Renin |
|---|---|
| Rennin is also called chymosin. | Renin is also called angiotensinogen. |
| These are protein- digesting enzymes | It is an aspartic protease protein and enzyme. |
| Rennin has an optimum PH 3.4 of for the proteolysis of bone serum albumin. | Renin is involved in the renin-angiotensin aldosterone system (RAAS), which regulates the body’s water balance and blood preserve level. |
| It is found in proteolytic enzymes found in the gastric juice of infants. | It regulates the body’s mean arterial blood pressure. |
| It acts upon milk protein ‘casein’. | |
| It is secreted by peptic (zymogen) cells of gastric glands into the stomach. | Renin originates from juxtaglomerular kidney cells. |
| This protein-digesting enzyme curdles milk by transforming caseinogen into insoluble casein. | The main function of renin is to hydrolyze angiotensinogen secreted from the liver into the peptide angiotensin I. |
Note: The commercial form of rennin is rennet. The rennet is used in manufacturing cheese. Renin catalyzes the conversion of a plasma protein called angiotensinogen.
