Question

How does carbohydrates digest in our body? explain?

Answer 1

The two digestible carbohydrates are starches and sugar, and both of these carbohydrates are digested or broken down into their most elemental form, along the gastrointestinal tract. Amylase, an enzyme which breaks apart starches, is found in the mouth and in the small intestine. Similarly, the three major enzymes which breaks apart sugar - sucrose, Maltase and lactose - are also found in the mouth and in the small intestine. Once these digested starches and sugar begin to move through the small intestine, they are able to be absorbed.

Answer 2

• The digestion of the proteins begin in the stomach where it is acted upon by the proteolytic enzyme of the stomach, pepsin. Pepsin converts proteins into proteoses and peptones (peptides).
• Proteins, proteoses and peptons in the chyme reaching the intestine are acted upon by the proteolytic enzymes (trypsin, chemotrypsin, carboxypeptidases) of the pancreatic juice and are converted into dipeptides.
• The enzymes in the succus entericus acts on the end product of the above reaction to form the simple absorbable forms.
• Dipeptidases present in the succus entericus converts the dipeptides into amino acids. Amino acids thus formed are absorbed in the jejunum and ileum regions of the small intestine.
