The hydrolysis of protein is initiated in the stomach by the enzyme pepsin. Pepsin breaks down proteins into smaller peptide fragments by cleaving the peptide bonds between amino acids.
Protein digestion begins in the stomach or abomasum of ruminants. Pepsin, an enzyme released in the stomach, helps break down proteins into smaller peptides. Further digestion of proteins occurs in the small intestine with the help of enzymes like trypsin and chymotrypsin.
Protein building begins in the cytoplasm of the cell with the process of transcription, where the DNA sequence coding for a specific protein is transcribed into a messenger RNA (mRNA) molecule. The mRNA then moves to the ribosomes in the cytoplasm, where translation occurs, and the amino acids are assembled in the correct order to form a protein.
At temperatures above 75°C, the structure of catechol oxidase begins to denature due to the disruption of weak intermolecular bonds within the protein. This denaturation causes the protein to lose its native folding and enzymatic activity, rendering it non-functional.
Chemical digestion of the starch starts in the mouth. Ptylin is the enzyme, which is secreted in the saliva. Ptylin breaks down the starch. This process continue in the stomach till acid neutralize the ptylin.
