Root Explanation

Pectinesterase → It is formed from "pectin" (from Greek "pektos", meaning thick or congealed) and "esterase" (from "ester" meaning a type of chemical compound and "-ase" indicating an enzyme). The word refers to an enzyme that breaks down pectin, a substance that thickens or gels.

Memory Tip

Think of 'pectin' which means something that thickens, and 'esterase' which indicates an enzyme. This helps you remember that pectinesterase is an enzyme that breaks down thickening substances.
