Pepsin is an enzyme used to catalyze the digestion of proteins (found in meat, egg etc.) in the stomach. It breaks down proteins into smaller units (polypeptides and amino acids) for easier digestion in the small intestine.
The Stomach is where Proteins are digested. This needs an acid environment and enzymes like pepsin. The digested proteins are not absorbed into the body by the stomach - this happens further down the alimentary tract.
Proteins are digested in the stomach. Pepsin is the enzyme, which is responsible for breaking the peptide bond of the proteins.
initiates protein digestion and denatures proteins
proteins
Proteins can denature with pH extremes. As the pH of stomach acid, e.g. hydrochloric acid, is 1 to 2, it is quite acidic and ingested proteins can denature within the stomach although I would stop short of saying that it is a function of the stomach.
The stomach digests the proteins in a meal. When it is finished digesting those proteins, the food leaves the stomach to be digested more and absorbed in the small intestine.
Proteins are first metabolized in the stomach, by the enzyme pepsin.
Proteins
Trypsin completes the digestion of proteins. Pepsin in the stomach starts the digestion of proteins.
Proteins
Emulsifying fats is not a function of the stomach. The stomach's main functions include churning food via peristalsis, breaking down proteins with digestive enzymes, and secreting hydrochloric acid for digestion.
