Digestion of carbohydrates − mouth and small intestine

Digestion of fats − small intestine

Digestion of proteins −  stomach and small intestine

Digestion of carbohydrates: Starch is digested in the mouth by salivary amylase. Other forms of carbohydrates are digested in the small intestine.

Starch + Salivary Amylase → Sucrose

Maltose + Maltase → Glucose

Lactose + Lactase → Glucose + Galactose

Digestion of Carbohydrates

Digestion of Proteins: Partial digestion of protein takes place in the stomach by gastric enzyme pepsin. Further digestion of protein happens in the small intestine.

Protein + Pepsin → Peptone + Proteose

(Protein + Peptone + Proteose) + (trypsin + chymotrypsin) → Dipeptides

Digesstion of Proteins

Digestion of Fat: Fat is at first emulsified by bile and then its digestion happens in the small intestine.

Fat + Lipase → Fatty acids + Glycerol
