Question

What is the maximum wavelengths of absorption for Chlorophyll A, Chlorophyll B, a-Carotene, Phenophytin A, and Xanthophyll (Cryptoxanthin)?

Answer 1

Chlorophyll A has maximum absorption wavelength at 430 nm and 660 nm

chlorophyll B has maximum absorption wavelength at 450 nm and 640 nm

alpha-carotene has the abosrption maxima in the range of 425 to 475 nm

Pheophytin A is basically the degradation pigment which is component of chlorophyll A and exhibit two maximum absorptions at 409 and 666 nm

xanthophylls shows the maximum absorption has range of 425 to 475 nm similar to carotene specifically at 435 nm
