Root Explanation

Peptidoglycan is formed from "peptido-" (from Greek "peptidos", meaning digestible or related to peptides) and "glycan" (from Greek "glykys", meaning sweet or sugar). The word refers to a polymer that consists of sugars and amino acids, forming a crucial component of bacterial cell walls.

Memory Tip

Think of 'peptido-' relating to 'digestible' or 'peptides' and 'glycan' meaning 'sugar' — together, they describe a substance made of sugars and amino acids that is essential for bacterial structure.
