Fucoidan

Fucoidan, known as Fucus polysaccharide, Fucoidan, Fucoidan,Fucoidan Sulfate, etc., mainly derived from brown algae, is a class of polysaccharides containing fucose and sulfate groups. It has a variety of biological functions, such as anti-coagulation, anti-tumor, anti-thrombosis, anti-virus, anti-oxidation and enhance the immune function of the body, so it is widely used in the field of medicine and modern food industry.

China is a large country of seaweed production and consumption, algae resources are abundant, especially brown algae resources are very important. Brown algae is attached to the life of low marine plants, of which the most common kelp. China's kelp culture area of 41000 km2, the annual output of more than 840000 t, both ranking first in the world, has formed a including breeding, breeding, food processing, algae chemical and biological products development of the seaweed industry, the annual output value of nearly 7 billion yuan. Brown algae seaweed is rich in polysaccharide components, such as kelp polysaccharide, agar, carrageenan polysaccharide (carrageenan) andSargassum fusiforme polysaccharide, etc., has become an important food or pharmaceutical raw materials and is widely used. In addition, the brown algae is also rich in fucoidan, which exists in the intercellular tissue of brown algae, and its content varies with the species, origin, season and different parts of the algae. Fucoidan is a water-soluble polysaccharide containing mainly fucose, a variety of monosaccharide residues and sulfate groups, and has biological activities such as anticoagulant, antitumor, antithrombotic, and antiviral. In the past 10 years, more and more experts and scholars have paid attention to the structure, biological function and the relationship between structure and function of fucoidan.
