Which of the following is not a vitamin?
(a) Trypsin
(b) Ascorbic add
(c) Riboflavin

(a) Trypsin
Trypsin is a digestive enzyme that helps to break down proteins into smaller peptide fragments. It is produced in the pancreas and secreted into the small intestine, where it helps to digest proteins in the food we eat. Trypsin works by cleaving the peptide bonds between amino acids in the protein molecule, which results in the production of smaller peptides and eventually individual amino acids that can be absorbed by the body. Trypsin is also used in various industries, including the food and pharmaceutical industries, for its ability to hydrolyze proteins.
