Chemical Digestion – Breakdown of Food by Enzymes

(Carb) Amylase

Breaks down starch into maltose.

(Carb) Maltase

Breaks down maltose into glucose.

(Carb) Sucrase

Breaks down sucrose into glucose and fructose.

(Carb) Lactase

Breaks down lactose into glucose and galactose.

(Protein) Pepsin

Breaks proteins into smaller peptides in the stomach.

(Protein) Pepsinogen

Inactive form of pepsin, activated by stomach acid.

(Protein) Trypsin

Breaks down proteins in the small intestine.

(Protein) Trypsinogen

Inactive form of trypsin, activated by enterokinase.

(Protein) Chymotrypsin

Further breaks down proteins.

(Protein) Carboxypeptidase

Breaks down peptides into amino acids.

(Protein) Peptidase

Breaks down peptides into individual amino acids.

(Protein) Enterokinase

Activates trypsinogen into trypsin.

(Fat) Lipase

Breaks down fats into glycerol and fatty acids.

(Fat) Bile

Aids in fat digestion by emulsifying lipids.
