Step 1: Understanding Biopolymers
Biopolymers are naturally occurring polymers produced by living organisms, including polysaccharides, proteins, and nucleic acids.
Step 2: Evaluating the Options
- Scleroglucan: A polysaccharide biopolymer produced by fungi.
- Aconitase: An enzyme, not a biopolymer.
- Lyase: An enzyme, not a biopolymer.
- Phenyl acetic acid: A small organic compound, not a biopolymer.
Step 3: Conclusion
Scleroglucan is the correct example of a biopolymer.
