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.
Proteins are obtained from nutrients of food. They starts to digest in stomach by proteases such as pepsin, trypsin in to peptides. These small peptides later digested further to form amino acids after complete digestion.
There are estimated to be tens of thousands of different proteins in the human body.
Small substances produced when proteins are digested are called amino acids. Amino acids are the building blocks of proteins and are absorbed by the body to use in various biological functions.
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.
In the small intestine
Digested.
Protein digestion primarily occurs in the stomach and small intestine of the human body.
Pepsin is an enzyme in the stomach that breaks down proteins into smaller molecules called peptides. It does this by breaking the bonds between the amino acids that make up proteins, which allows the body to absorb and use the nutrients from the digested proteins.
