Root Explanation

Aglycone is formed from "a-" (meaning without) and "glycone" (from Greek "glykys", meaning sweet). The term refers to a molecule that is without a sugar component, specifically in the context of glycosides where the aglycone is the non-sugar part.

Memory Tip

Think of 'a-' meaning 'without' and 'glycone' relating to 'sweet' — so an aglycone is something that is without sweetness.
