How is fucoxanthin measured? Brown algae usually have a holdfast. In this work, the ameliorative effect of fucoxanthin on visible light and lipid peroxidation-induced phagocytosis disruption in retinal pigment epithelium (RPE) cells was investigated in vitro. 1972). They are characterized by the pigment fucoxanthin and by the use of oil droplets as a food reserve. Numerous studies have shown that fucoxanthin has considerable potential and promising applications in human health. 5. In particular, fucoxanthin makes up a major part of the carotenoids in brown algae. The algae are classified on the basis of their pigment composition. The brown algae contain the fucoxanthin pigment and different pheophycean tannins that are responsible for the characteristic greenish-brown color like the name indicated.
