The major chemical digestive activity occurring in the stomach is digestion of protein.
- The mechanical and chemical breakdown of food into small organic particles is known as digestion.
- It is crucial to breakdown large molecules into smaller pieces that can pass through the digestive epithelium and be absorbed.
- Protein digestion happens largely in the stomach. By converting intact proteins into peptides, which are short chains of amino acids made up of four to nine amino acids, the enzyme pepsin plays a crucial part in the digestion of proteins.
- Other enzymes, such as trypsin, elastase, and chymotrypsin, operate on the peptides in the duodenum, breaking them down into smaller peptides.
- The pancreas produces trypsin, carboxypeptidase, and chymotrypsin, which are then secreted into the duodenum where they act on the chyme.
- Absorption through the small intestines allow the amino acids to enter the blood circulation.
