In 1846 Claude Bernard demonstrated a lipase activity
in the pancreas. The existence of lipases in plant seeds was noted by Munz MA (Ann Chem Liebigs 1871)

Lipase is the enzyme that catalyzes the hydrolysis of
lipids (fats) such as pancreatic which facilitates the absorbion of fats by the
intestines . Lipases are glycerol ester hydrolases that act on acylglycerols to
liberate fatty acids and glycerol.
