|
|
Term
|
Definition
| a proteolytic enzyme produced by the stomach |
|
|
Term
|
Definition
| a milk-curdling enzyme present in the gastric juice of young mammals |
|
|
Term
|
Definition
| coasts the lining of the stomach and prevents the tissue from being digested by the digestive secretions produced by the other tissues found in the stomach |
