Question

In jejunum, which of the following enzymes is required for the digestion of amino acid containing compounds?

• A. Chymotrypsin
• B. Pepsin
• C. Trypsin
• D. Peptidase

Answer 1

Answer: (D)

Peptidase

Peptidases are the intestinal proteases, which act on peptides as follows:
$Polypeptide\underset{Alkalinemedium}{\overset{Polypeptidase}{\to }}Dipeptides$

$Dipeptide\underset{Dipeptidase}{\overset{Alkalinemedium}{\to }}Aminoacids$
Pepsin, trypsin, and chymotrypsin, etc are aminopeptidases, which act upon amino groups of the peptide bond.

Thus the correct answer is option D.
