1897Jrnl. Chem. Soc. LXXII. ii. 150 The active enzyme, for which the name lipase is suggested, is also capable of acting..on the natural oils and fats. 1946Nature 14 Sept. 375/1 It thus appears that there are at least two distinctly different enzymes (or enzyme systems) present in these glycerol extracts: (1) a lipase, hydrolysing esters of glycerol..; and (2) an esterase, hydrolysing esters of lower alcohols than glycerol. 1955Sci. Amer. Oct. 70/2 Some enzymes (e.g., amylase and lipase) work in the digestive system, breaking up the crude food material into simpler parts which can be transported by the bloodstream. 1970R. W.
