Question

Sporopollenin is formed by the polymerization of

• A. Fat and phenols
• B. Fats and esters
• C. Carotenoids and fat
• D. Carotenoid and esters

Answer 1

Answer: (A)

Fat and phenols

Sporopollenin is composed of carbon, hydrogen, and oxygen, though the exact chemical composition is not known, due to its unusual chemical stability and resistance to degradation by enzymes and strong chemical reagents. Analyses have revealed a mixture of biopolymers, containing mainly long chain fatty acids, phenylpropanoids, phenolics and traces of carotenoids.

So the correct option is 'Fats and phenols'.
