Final answer:
Peptidases on the surface of small intestinal cells, such as aminopeptidases, carboxypeptidase, dipeptidase, and aminopeptidase, hydrolyze peptides by breaking peptide bonds. They assist in digesting proteins into smaller peptides and individual amino acids for absorption.
Step-by-step explanation:
Peptidases found on the surface of small intestinal cells include aminopeptidases, carboxypeptidase, dipeptidase, and aminopeptidase. These enzymes hydrolyze peptides by breaking the peptide bonds between amino acids. Aminopeptidases remove amino acids from the N-terminal end of peptides, while carboxypeptidase hydrolyzes peptide linkages at the free carboxyl end of the peptide chain. Dipeptidase breaks down dipeptides into individual amino acids. By catalyzing these hydrolysis reactions, these peptidases help in the digestion of proteins into smaller peptides and eventually into individual amino acids for absorption.
Peptidases on the surface of small intestinal cells such as carboxypeptidase, dipeptidase, and aminopeptidase are crucial for breaking down peptides into amino acids, which are then absorbed into the bloodstream for protein synthesis.
Peptidases found on the surface of small intestinal cells include carboxypeptidase, dipeptidase, and aminopeptidase. These enzymes play a crucial role in protein digestion, breaking down peptides into individual amino acids. The carboxypeptidase catalyzes the hydrolysis of peptide linkages at the free carboxyl end of a peptide chain. Aminopeptidase removes amino acids from the N-terminal end of peptides possessing a free amino group. And dipeptidase hydrolyzes dipeptides into two separate amino acids.
Protein digestion begins in the stomach with the enzyme pepsin and continues in the small intestine with the involvement of pancreatic enzymes like trypsin and chymotrypsin, which activate further enzymes that break down peptides. This process is completed in the small intestine with peptidases that hydrolyze these peptides, resulting in amino acids that can be absorbed across the intestinal wall into the circulatory system for use in protein synthesis.
