What would happen if we didn't have pepsin?
A chemical process called hydrolysis breaks down a protein's bonds by converting them into smaller chains called polypeptides and smaller units called amino acids.The health of you and your family would be at risk without the ability to digest proteins.
Why does pepsin not function in the small intestine?The role of pepsin in digestion is limited because it is only active in the stomach and not the small intestine where the luminal pH is neutral.
A protease is an endopeptidase that breaks down proteins into smaller peptides.It is produced in the stomach and is one of the main digesters in humans and many other animals.
The carboxylic acid group in pepsin's active site must be bound to a hydrogen atom to function best at pH 2.The carboxylic acid group is able to break chemical bonds at low pH.
