Question

how do carbohydrates proteins and fats get digested in ourhuman beings

Answer 1

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 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

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

Fat + Lipase → Fatty acids + Glycerol

Answer 2

In our human beings the carbohydrates are digested by the enzymes, called SALIVARY AMYLASE and PANCREATIC AMYLASE. Fats are emulsified by the bile juice and digested by PANCREATIC LIPASE. Proteins are digested by PEPSIN and TRYPSIN.
