The carbohydrates, proteins and fats are digested in small intestine .The enzymes present in the small intestine convert carbohydrates into glucose , fats into fatty acid and glycerol and proteins into amino acidHope this will help ? you..
Digestion in human beings starts from mouth. In mouth, saliva is mixed with food. Salivary amylase or ptylin breaks starch (complex carbohydrates) into maltose and isomaltose and its further digestion is carried out by enzymes present in intestinal juice and pancreatic juice. Pesin breaks peptide bond of protein. Tripsin and peptidase further breaks protein into amino acid. Pancreatic lipase convertes fats into fatty acid and glycerol
Carbohydrates, proteins, and fats are digested in the intestine, where they are broken down into their basic units: Carbohydrates into sugars. Proteins into amino acids. Fats into fatty acids and glycerol.
