Product description:

We have Extracted Hyaluronic acid and Fermented hyaluronic acid with three grades(Pharma Grade,food grade, Cosmetic Grade)

Extracted Hyaluronic Acid is extracted from rooster combs.It is very similar to the natural Hyaluronic Acid in human body.Naturalness,activity,low molecular weight and easy absorbed make Extracted Hyaluronic Acid very popular in the Nutritional Supplyment and Cosmetics manufacturing.

Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc.The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million. It is aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food.

Synonyms: hyaluronan;HA;beta-D-glucopyranuronosyl-(1->3)-(3xi)-2-(acetylamino)-2-deoxy-beta-D-ribo-hexopyranosyl-(1->4)-beta-D-glucopyranuronosyl-(1->3)-(3xi)-2-(acetylamino)-2-deoxy-beta-D-ribo-hexopyranose;beta-D-glucopyranose, O-beta-D-glucopyranuronosyl-(1->3)-O-2-(acetylamino)-2-deoxy-beta-D-glucopyranosyl-(1->4)-O-beta-D-glucopyranuronosyl-(1->3)-2-(acetylamino)-2-deoxy-, monosodium salt;sodium (2S,3S,4R,5R,6R)-3-{[(2S,3R,5S,6R)-3-(acetylamino)-5-hydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl]oxy}-4,5,6-trihydroxytetrahydro-2H-pyran-2-carboxylate (non-preferred name);(3S,4R,5R,6R)-3-[(2S,3R,5S,6R)-3-acetamido-4-[(2S,3R,4S,6S)-6-carboxy-3,4,5-trihydroxy-tetrahydropyran-2-yl]oxy-5-hydroxy-6-(hydroxymethyl)tetrahydropyran-2-yl]oxy-6-[(3R,4R,5S,6R)-3-acetamido-2,5-dihydroxy-6-(hydroxymethyl)tetrahydropyran-4-yl]oxy-4,5-dihydroxy-tetrahydropyran-2-carboxylic acid;
