Question

How are polysaccharides and disaccharides digested?

✓

Answer

Digestion of carbohydrates takes place in the mouth and the small intestine. The enzymes carbohydrases act on carbohydrates. As the food enters the mouth, it gets mixed with saliva and breaks down starch into maltose, isomaltose and limit dextrins. The digestion of carbohydrates does not take place in the stomach. In the small intestine, the food gets mixed with pancreatic juice and intestinal juice. Pancreatic juice contains pancreatic amylase which digests polysaccharides into disaccharides.$\text{polysaccharides}\xrightarrow[]{\text{Anylase}}\text{Disaccharides} $
Intestinal juice also contains a variety of enzymes which digest the disaccharides into glucose, fructose and galactose.

Sakshi's biology teacher was explaining about the digestion in human beings and the enzymes responsible for digestion. During that time, Sakshi was busy completing work of some other subject. So, she did not understand the topic completely. Sakshi reached home asked her elder sister (a biology graduation student) about the role of HCI in our digestive system as she had heard it in her biology class. She also asked her sister that it was surprising because she had only studied about HCI in chemistry that it is a strong acid to be used in industries and labs, then how is it useful in our body in protein digestion. Her sister clarified her doubts about the difference between the types of HCI used in labs and produced in our body:
