  • Polysaccharides (starch) →Disaccharides (maltose, sucrose, lactose, isomaltose and dextrins) →Monosaccharides (glucose, fructose and galactose)

  • Fats →fatty acids and glycerol

  • Proteins →Peptones → Peptides→Amino acids

  • Nucleic acids →Nucleotides →Nucleosides and phosphate →Nitrogen bases and pentose phosphate.

A specific digestive enzyme carries out each reaction. Process of digestion mostly requires hydrolysis and water molecules are used for the cleavage. Hydrolysis is a… (33 more words) …
