Root Explanation

Phosphorylate → It is formed from "phosphorus" (from Greek "phosphoros", meaning light-bringer or morning star) and "-ylate" (a suffix used in chemistry to indicate the addition of a group). The word "phosphorylate" means to add a phosphate group to a molecule, often in the context of biochemistry.

Memory Tip

Think of 'phosphorus' as the 'light-bringer' that adds a 'group' to a molecule, which is what happens during phosphorylation.
