Question

what is main role pepsinogen in digest ​

Answer 1

Explanation:

Pepsin is most efficient in cleaving peptide bonds between hydrophobic and preferably aromatic amino acids such as phenylalanine, tryptophan, and tyrosine.[3]

Pepsin's proenzyme, pepsinogen, is released by the chief cells in the stomach wall, and upon mixing with the hydrochloric acid of the gastric juice, pepsinogen activates to become pepsin.[2]

Answer 2

Answer:

Pepsin is an endopeptidase and can digest peptide bonds, the predominant chemical bond found in proteins. Pepsin's main role is to digest proteins found in food. Because of pepsin's dependence on an acidic environment for it to digest protein, pepsin is most active around a pH of 1.5 to 2
