The examples of pigments having benzopyran derivatives is:
The examples of pigments having benzopyran derivatives is:
Show Hint
Flavonoids are "C6-C3-C6" compounds. The central C3 unit along with part of a C6 ring forms the characteristic benzopyran derivative core.
Updated On: Jul 4, 2026
- Chlorophylls and bilins
- Carotenoids
- Anthocyanins and flavonoids
- Melanoidins and caramels
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Pigments are often classified by their core chemical backbone.
• Carotenoids are tetraterpenoids.
• Chlorophylls are tetrapyrroles.
• Flavonoids have a 15-carbon skeleton with two phenyl rings.
Step 1: Understanding the Benzopyran structure.
Benzopyran (also called chromene) is a polycyclic compound. It consists of a benzene ring fused to a pyran ring.
Step 2: Relating to Flavonoids.
Flavonoids are built upon a 2-phenyl-chromen-4-one backbone. Anthocyanins are a specific class of flavonoids.
Step 3: Analyzing the function.
These pigments provide red, purple, and blue colors to plants. They are water-soluble and stored in the vacuole. Final Answer: (C)
