Root Explanation

Glycosidase is formed from "glyco-" (from Greek "glykys", meaning sweet) and "-sidase" (from Latin "caedere", meaning to cut). The term refers to an enzyme that cuts glycosidic bonds in carbohydrates, thus relating to the sweet nature of sugars.

Memory Tip

Think of 'sweet' ('glyco-') being 'cut' ('-sidase') by an enzyme, which helps you remember that glycosidase is an enzyme that cuts sugar bonds.
