All plants and animals have enzymes, that is, biological enzymes, which are necessary intermediate catalysts for the survival of the body. There are more than 5000 kinds, each of which has a different function.

Enzymes are actually biological enzymes, such as trypsin and chymotrypsin, which can catalyze the decomposition of protein. This principle has been used in surgical wound dilation, purulent wound purification and the treatment of serosa adhesion in thorax and abdomen. And they are all specific drugs and can't be eaten casually.

Biological enzyme, that is, the enzyme promoted by some businesses, is generally called biological enzyme by regular businesses. Any metabolism will produce biological enzymes. For example, when we eat, we secrete sialidase and there is pepsin in our stomach. These are catalysts for metabolism, which are produced by other organisms. If we eat it in the stomach, the effect will be different, and it will be decomposed by gastric acid. Otherwise, the metabolic catalysts of other organisms are catalyzed in the human body, which is a mess.

Enzymes are biological enzymes, and the functions of oral enzymes have not been scientifically verified.
