Detailed explanation-1: -Although the body can synthesize proteins from amino acids, food is an important source of those amino acids, especially because humans cannot synthesize all of the 20 amino acids used to build proteins. The digestion of proteins begins in the stomach.
Detailed explanation-2: -During digestion, proteins are broken down into amino acids through hydrolysis. The amino acids dissolve in our blood and are carried to tissues and organs.
Detailed explanation-3: -The two major pancreatic enzymes that digest proteins in the small intestine are chymotrypsin and trypsin . Trypsin activates other protein-digesting enzymes called proteases, and together, these enzymes break proteins down to tripeptides, dipeptides, and individual amino acids.
Detailed explanation-4: -Protein is not usually used for energy. However, if the body is not getting enough calories from other nutrients or from the fat stored in the body, protein is broken down into ketone bodies to be used for energy.
