Which of the following is a naturally occurring condensation co-polymer?

1. Natural rubber
2. Starch
3. Insulin
4. Dacron

Correct answer: Insulin

Solution

Insulin is a naturally occurring condensation co-polymer made of two different polypeptide chains (A and B chains) composed of multiple different amino acids joined by peptide bonds (condensation) — it qualifies as a natural condensation co-polymer. Starch is a condensation homo-polymer (only glucose units). Natural rubber is an addition polymer of isoprene. Dacron is a synthetic condensation co-polymer.
