is an alga of thallus of greenish -

pedicle that is at the base. Is fitted, in
reproduction, conceptáculos unisexuados.
The fucose stretch in the cold waters of the globe specifically in the area mediolitoral:

The thallus of fucose - rich polyols are mannitol, sorbitoland polysaccharides: fucoidano (SS1 polymer? Fucose Sulphated 2) laminarana (glucosana (ß - 1? 3) mucopolysaccharides "Lectin like"And, above all, Algin or alginic acid.

, etc) Industrially are prepared alginates from various Feoficeas:
Fucose are described in other compounds:
acrylic acid, carotenoids (eg fucoxanthin) lipids, represented mainly by phospholipids and polar glucolípidos, sterols, halogens (

, phenols. These are the phenols Phloroglucinol (1, 3, 5 - trihydroxy - benzene) and its oligomers, which carry two to seven units preferably linked by bridges ether, more rarely by bridges biphenyls. The floroglucinol is also in the form of polymer 
Alginic acid and

mechanical protection of the gastric mucosa and form

alginate leads to precipitation of alginic acid in situ and in the presence of
dioxide is added to the gel off by ensuring the survivability of it.
alginate is hemostatic, is harmless to the wounds and easily reasorbible.

Apparently the fucose lack of toxicity (acute toxicity test: 3g / kg, subacute toxicity test: 300 and 600 mg / kg / day, criomolturado, rat, per os) They are used in powdered form in doses of 0. 5 to 2 g / day, in case of

The use of alginates and Algin in pharmacy is manifold: for its physiological properties (
