What substance responsible for breaking down proteins in Animal body?

Glycine Amino Acid Illustration by OpenClipart-Vectors|Glycine is the simplest amino acid, which is a building block of proteins.

In the animal body, the substance that is primarily responsible for breaking down proteins is enzymes called proteases. Proteases are a type of enzyme that catalyze the hydrolysis of peptide bonds, which are the chemical bonds that link amino acids together in proteins. Proteases are produced by various organs and tissues throughout the body, including the stomach, pancreas, and small intestine.

In the stomach, the protease pepsin is secreted and starts breaking down proteins into smaller peptides. In the small intestine, various proteases produced by the pancreas, including trypsin, chymotrypsin, and carboxypeptidase, further break down peptides into amino acids. These amino acids are then absorbed into the bloodstream and transported to various tissues where they are used to build new proteins or for other metabolic processes.

Proteases are a type of enzyme that catalyze the hydrolysis of peptide bonds between amino acids in proteins, which results in the breakdown of proteins into smaller peptides and eventually into individual amino acids. Proteases are also known as proteinases, peptidases, or proteolytic enzymes.

Proteases are involved in many important biological processes, including digestion, blood coagulation, immune system function, and protein turnover. They are produced by various organs and tissues throughout the body, including the stomach, pancreas, liver, and small intestine.

The 4 types of proteases

1. Serine proteases - These proteases contain a serine amino acid in their active site and are involved in blood clotting, digestion, and other processes.

2. Cysteine proteases - These proteases contain a cysteine amino acid in their active site and are involved in cellular processes such as apoptosis and protein turnover.

3. Aspartic proteases - These proteases contain an aspartic acid amino acid in their active site and are involved in digestion and other processes.

4. Metalloproteases - These proteases require a metal ion, usually zinc, in their active site and are involved in a wide range of biological processes, including wound healing and inflammation.
