Question

After digestion of proteins, what products are absorbed into the circulation? ​

Quizplus · Accepted Answer

During the digestion of proteins, the enzymes break down the protein molecules into smaller peptides and free amino acids. Dipeptides and tripeptides are also produced during this breakdown. However, only free amino acids and a few dipeptides and tripeptides are absorbed into the circulation. The majority of dipeptides and tripeptides are further broken down into free amino acids inside the intestinal cells before being transported into the bloodstream. Therefore, option D is the best choice.
