HUMAN NUTRITION

Detailed explanation-1: -During digestion, proteins are broken down into amino acids through hydrolysis. The amino acids can dissolve in the blood and are transported to tissues and organs. Body requires amino acid supplements to build up proteins. Amino acids are of two types namely, essential and nonessential amino acids.

Detailed explanation-2: -Enzymes in the stomach and small intestine break down proteins into amino acids.

Detailed explanation-3: -Protein catabolism is the breakdown of proteins into absorbable monomers for further degradation or reassembly. Protein catabolism in the intestinal lumen is important for several reasons, one of which is mobilizing essential amino acids for absorption.

Detailed explanation-4: -Hint: Protein is a very important nutrient in our food but the dietary protein is too large to be absorbed directly by our cells. Therefore, its digestion occurs in the alimentary canal to break it into small amino acid molecules that can be absorbed by our body.
