Digestion is a process where the food is broken down by the mechanical and chemical process. Protein is chiefly digested in the stomach. The complex form of protein is digested into the simple form by pepsin and HCL present in the stomach. It converts Proteins into Peptides and Polypeptides.

Which of this is digested in the stomach?

Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.

What are not digested in the stomach?

Fats and carbohydrates are the only food components that are not digested in the stomach. This is mainly because amylase enzymes can function only in alkaline conditions and are absent in the human digestive system. Therefore, fats and carbohydrates are mostly digested and are readily absorbed by the small intestine.
