Carbohydrate:
Digestion in the Oral Cavity. When food is taken in through the mouth, chewing and mixing of the food occurs. There is also a chemical breakdown of carbohydrates, due to the action of saliva from the salivary glands. 30% of the starch is hydrolyzed by the action of amylase, which is a salivary enzyme.
Fat and protein:
Bile makes the food alkaline for the action of pancreatic and intestinal enzymes in the small intestine. *Bile brings about emulsification of fats which are later digested by intestinal lipases. The pancreas secretes pancreatic juice which includes trypsin and lipases that help break down proteins and fats.
