Question

Examples of pigments benzopyran derivatives:

• A. Chlorophyll and hemes
• B. Carotenoids and anthocyanins
• C. Anthocyanins and flavonoids
• D. Anthocyanins and hemes

Hint:

When studying plant pigments, remember that anthocyanins and flavonoids are common examples of benzopyran derivatives responsible for many colors in fruits, flowers, and leaves.

Answer 1

The Correct Option is C

Benzopyran derivatives are organic compounds that contain a benzene ring fused with a pyran ring. These derivatives are important in the structure of various plant pigments. The correct combination of pigments that are benzopyran derivatives are anthocyanins and flavonoids. These pigments are responsible for a wide range of colors in plants and are considered derivatives of the benzopyran structure.
- Chlorophyll and hemes: Chlorophyll is not a benzopyran derivative; it is a porphyrin-based compound.
- Carotenoids and anthocyanins: Carotenoids are also not benzopyran derivatives. They are terpene-based pigments.
- Anthocyanins and flavonoids: Correct! Both of these pigments are derived from the benzopyran structure.
- Anthocyanins and hemes: Heme is not a benzopyran derivative. It is a porphyrin derivative.
Thus, the correct answer is (3) Anthocyanins and flavonoids.
