Overview of Fucoidan
Upload a video

The marine macroalgae produce a collection of bioactive polysaccharides, of which the sulfated heteropolysaccharide fucoidan produced by brown algae of the class Phaeophyceae has received worldwide attention because of its particular biological actions that confer nutritional and health benefits to humans and animals. The biological actions of fucoidan are determined by their structure and chemical composition, which are largely influenced by the geographical location, harvest season, extraction process, etc.

    1. Marine Macroalgal Sources of Fucoidan

    Macroalgae, also called seaweeds, are taxonomically categorized into the phyla Chlorophyta (green algae), Rhodophyta (red algae) and Phaeophyta (brown algae). Brown seaweeds are benthic, and they inhabit the coastal ecosystems in temperate and cold-water seas [1]. Brown macroalgae produce the fucoidan polysaccharide [2] (Table 1). The brown seaweeds, such as Ecklonia cavaAscophyllum nodosumCladosiphon okamuranusUndaria pinnatifidaSaccharina longicrurisSaccharina latissimaSargassum polycystumLaminaria japonicaFucus vesiculosus and Fucus serratus, are abundant sources of fucoidans [3][4][5][6][7][8][9].
