Root Explanation

Polyhydroxy → It is formed from "poly-" (from Greek "polus", meaning many) and "hydroxy" (from Greek "hydro" meaning water and "oxy" meaning oxygen). The word refers to a compound that contains many hydroxyl groups, which are functional groups consisting of oxygen and hydrogen, thus relating to the presence of multiple water-like characteristics.

Memory Tip

Think of 'many' ('poly-') hydroxyl groups, which are made of 'water' ('hydro') and 'oxygen' ('oxy'). This helps you remember that 'polyhydroxy' refers to a substance with many water-like properties.
