Basic Description
| Product Name | Rennin from calf stomach, CAS No.9001-98-3 |
|---|---|
| Product Description |
Rennin, also known as chymosin, is a milkclotting acid proteinase produced in the stomach of a calf. It is used in cheesemaking and to study neonatal gastric digestion . |
| Specifications & Purity | ≥20 units/mg protein |
| Biochemical and Physiological Mechanisms | Rennin, a 323 amino acid chain, is secreted as an inactive precursor which is then converted into an active enzyme through limited proteolysis. It cleaves the peptide bond between phenylalanine and methionine in K-Casein. |

| Description | This compound belongs to the class of organic compounds known as cyclic depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating. |
