Digestions refers to the breaking down of food (larger molecules) into smaller absorb-able units.
Chemical digestion refers to digestion of food with the help of chemicals such enzymes, acid, and bile.
Enzymes are the main type of chemicals which hydrolysis (breaking down of compound with the help of water) the macro-molecules such as polysaccharides, polypeptides, et cetera into smaller and simpler units.
For example, amylase hydrolyse polysaccharides into smaller units such as maltose and glucose; trypsin, chymotrypsin, pepsin are enzymes which hydrolyze polypeptides into amino acids, nucleases are the enzymes which help in hydrolysis of nucleic acids, et cetera.
Bile and lipases help in emulsification of fats.
