NAME: Alginic Acid
CAS NUMBER:9005-32-7
HS CODE:39131000
Description:
Alginic Acid, a polysaccharide extracted from kelp-like Phaeophyceae, formed by L-Mannuronic acid (M section) and D-Guluronic acid (G section), connected through 1,4-glucosidic bond. Alginate acid is unstable, and it can react with positive metal ions to form a series of alginate products.
