People with the rare metabolic disorder lysinuric protein intolerance cannot properly digest proteins. which of the following enzymes may be defective in this disorder? hint: think about protein digestion?
1. trypsin
2. carboxypeptidase
3. maltase
4. salivary amylase
5. gastric lipase

Explanation:

Trypsin is a peptidase or protease enzyme, which breaks the peptide bonds of proteins by hydrolysis to form smaller peptides and amino acids. Actually, it's an enzime that catalyzes the breaking down process of proteins.

Trypsin is produced in the pancreas and secreted in the duodenum (part of the intestine), where it is essential for digestion.

So, basically, trypsin is the enzyme among the options that intervenes in the proteins breaking down process, making it smaller which produces aminoacids.

Therefore, the right answer is Trypsin, because it's the enzyme responsible for the digestion of proteins molecules.
