प्रश्न
How do carbohydrates, proteins and fats get digested in human beings?
उत्तर
- Carbohydrate Digestion - Digestion of carbohydrates starts with buccal cavity where salivary enzymes break down the starch into simple sugar molecules. Other sugar molecules break down to glucose in the small intestine.
- Protein digestion - Proteins are partially digested by pepsin secreted by gastric glands present in the stomach. Then Pancreatic juice secrets trypsin and chymotrypsin enzymes in the small intestine where complete digestion of proteins takes place.
- Fat Digestion - Fats are digested in the small intestine. Bile juice present in the liver emulsifies the fat which breaks fats into small globules. These small fat globules are converted into glycerol and fatty acids by Lipase enzyme.
