Example

Cystine is essential for the strength and stability of keratin in hair.

Conversation

I read that cystine plays a big role in protein structure.

Really? I had no idea it was that important.

Yeah, it helps stabilize proteins like keratin in our hair and nails.

That makes sense! I guess it's crucial for keeping them healthy.

Root Explanation

Cystine is derived from "cystis" (from Greek "kystis", meaning bladder or sac) and the suffix "-ine" (used in chemistry to denote substances). The word refers to a specific amino acid that is found in the body, often associated with the bladder or sac-like structures in biological contexts.

Memory Tip

Think of 'cystis' meaning a 'sac' or 'bladder' — this helps you remember that cystine is related to structures in the body.
