Diadinoxanthin is a pigment found in phytoplankton. It has the formula C40H54O3. It gives rise to the xanthophylls diatoxanthin and dinoxanthin. Diadinoxanthin is a plastid pigment. Plastid pigments include chlorophylls a and c, fucoxanthin, heteroxanthin, diatoxanthin, and diadinoxanthin. Diadinoxanthin is a carotenoid. It is found in diatoms, along with other caroten… Web鉴于此，马克斯-普朗克研究所Stefan W. Hell、Alexey N.
