Pepsin starts digestion of proteins by breaking down the many of polypeptides into shorter peptides.
The body breaks digested proteins into amino acids
All the proteins in the food is consumed. Once it enters the body it has to be digested to amino acids and not the proteins in the food directly go and attach in human cells.
Food has to be digested so our body can get the proteins and nutrients etc. out of it, food is the fuel for the body
Proteins you eat are 'Foreign proteins' to your body. If they enter like that in your body will provoke immunological response. So they must be separated to individual Amine acids and absorbed. They will be 'rearranged' according to the need of the body to form body proteins.
The Stomach is where Proteins are digested. This needs an acid environment and enzymes like pepsin. The digested proteins are not absorbed into the body by the stomach - this happens further down the alimentary tract.
Digested.
In the small intestine
All the proteins in the human body are harmless. The protein which may be look harmless may cause deleterious effect when injected directly into our blood. This is because the engulfed proteins in food are digested by our digestive system since they are not harmful. But the same may not true if injected.
it is digested to your muscles.
The orginal source doesn't matter once proteins are digested to animo acids.
