Root Explanation

Racemate → It is formed from "racemus" (from Latin, meaning a bunch of grapes) and the suffix "-ate" (indicating a chemical compound). The word refers to a compound that contains equal amounts of two enantiomers, akin to a bunch of grapes containing different varieties.

Memory Tip

Think of a 'bunch of grapes' ('racemus') to remember that 'racemate' refers to a mixture of two forms of a compound, just like a bunch can have different types of grapes.
