Interesting Fact
Fucoxanthin Gives Brown Seaweed Its Distinctive Color
Fucoxanthin is a naturally occurring pigment that gives brown seaweed, such as wakame and kombu, their characteristic brownish or olive-green shade. Found in the chloroplasts of these marine plants, fucoxanthin helps them capture light for photosynthesis, especially in the blue-green part of the spectrum where sunlight penetrates deeper into the ocean.
