Explanation:
Amino acids are the building blocks of proteins. Proteins are digested in the gastrointestinal tract into peptides,polypeptides and single amino acids using hydrochloric acid and proteases.

They then travel in the blood to the liver, joins the urea cycle where they are metabolised for cell growth and tissue repairs.
