Conversation

Hey, do you remember that biology class where we learned about proteoglycan?

Yeah, it was fascinating how they are part of the extracellular matrix.

Right? I didn't realize how important proteoglycan is for connective tissue.

Exactly! It really helps to understand how our bodies function.

Root Explanation

Proteoglycan → It is formed from "proto-" (from Greek 'protos', meaning first) and "glycan" (from Greek 'glykys', meaning sweet or sugar). The word refers to a class of molecules that are primarily composed of sugars and are essential components of the extracellular matrix in tissues.

Memory Tip

Think of 'first' ('proto-') and 'sugar' ('glycan') to remember that proteoglycans are important molecules made primarily of sugars.
