Fucoxanthin

C₄₀H₅₆O₆, a yellow carotenoid pigment found in diatoms and in brown and golden algae; a xanthophyll. Fucoxanthin occurs in algae together with chlorophyll, the basic photosynthetic pigment. The absorption spectrum of fucoxanthin in the visible region has three maxima—at 424–436, 448–460, and 471—492 nanometers. No flourescence has been detected. Fucoxanthin takes part in photosynthesis by ensuring the transfer of absorbed luminous energy to chlorophyll. The high efficiency of the energy transfer indicates that fucoxanthin is located in close proximity to chlorophyll.
