What are the enzymes in the human body?

There are many kinds of hydrolases such as pepsin and trypsin in human body. Protein ingested by human body from food must be hydrolyzed into amino acids under the action of enzymes such as pepsin, and then more than 20 kinds of amino acids needed by human body are selected and recombined into various protein needed by human body in a certain order.

As a big classification, enzymes can be divided into catabolic enzymes and synthetic enzymes. For example, protein is broken down into amino acids of a size that can be absorbed (like that), and the protein necessary for human body is synthesized by decomposing enzymes and absorbed amino acids, both of which are based on enzymes.

However, in order to distinguish the enzymes used in vivo from those used in vitro, it can also be said that the enzymes used in living tissues are called "metabolic enzymes" and the enzymes used outside living tissues such as intestines and stomach are called "digestive enzymes" for convenience. Biochemistry can be divided into six categories: acidifying reductase, transferases, hydrolases, dissociative enzymes, heterotypic enzymes and synthetic enzymes.

Extended data:

Enzyme is a biocatalyst, which dominates many catalytic processes such as metabolism, nutrition and energy conversion. Most of the reactions closely related to life processes are enzyme-catalyzed reactions.

Enzymes digest and absorb food eaten by human body, and maintain all functions of internal organs, including cell repair, anti-inflammation, detoxification, metabolism, improving immunity, generating energy and promoting blood circulation. For example, when rice is chewed in the mouth, the longer the chewing time, the more obvious the sweetness, because the starch in rice is hydrolyzed into maltose under the action of salivary amylase secreted by the mouth. Therefore, chewing more when eating can make food and saliva fully mixed, which is beneficial to digestion.
