Detailed explanation-1: -When babies first begin to eat solid foods they are not very good at digesting protein. Treating the food with protease enzymes makes it easier for a baby’s digestive system to cope with it as they predigest some of the protein. It is then easier for them to get the amino acids they need from the food. 3.

Detailed explanation-2: -The most widely used enzymes are hydrolases such as proteases, lipases, and carbohydrases. Proteases are used for the in vitro digestion of milk protein for use in infant formulas. The hydrolyzed protein formulas offer complete nutrition for babies that may be allergic to cow’s milk protein.

Detailed explanation-3: -The two major pancreatic enzymes that digest proteins are chymotrypsin and trypsin. The cells that line the small intestine release additional enzymes that finally break apart the smaller protein fragments into the individual amino acids.

Detailed explanation-4: -Hint: Rennin is an enzyme found mostly in infants which helps in the digestion of milk proteins. Complete answer: Rennin is a proteolytic enzyme found in the gastric juice in the stomach of infants which helps in the digestion of Casein (milk protein). Rennin is also known as Chymosin synthesized by the chief cells.

Detailed explanation-5: -Protein digestion first begins in the stomach, where pepsinogen is converted to active form pepsin, by hydrochloric acid. Pepsin breaks proteins down into polypeptides.
