what are the step involved in the direction of protein in a given food sample answer in 50 to 100 words

Dear student,
The d
igestion of proteins begins in the stomach and is completed in the small intestine. The enzymes that act on proteins are known as proteases.

Digestion in the stomach

The acidic medium converts inactive pepsinogen into active pepsin.

Proteins Proteases + Peptides

Digestion in the small intestine:

The food is acted upon by three enzymes 

Action of pancreatic juice

Trypsinogen Trypsin + Inactive peptide

The activated trypsin then activates the other enzymes of pancreatic juice.

Chymotrypsinogen Chymotrypsin

Proteins Peptides

Peptides Smaller peptide chain + Amino acids

Action of bile juice

Bile juice breaks down large, fat globules into smaller globules so that pancreatic enzymes can easily act on them. 

Action of intestinal juice

Intestinal juice contains a variety of enzymes. 

Eg 

The proteases hydrolyse peptides into dipeptides and finally into amino acids.

Dipeptides Amino acids
