Description

Application

Acid hydrolysates of alginic acid can be used to prepare a-1,4-~-Polyguluronic and B- 1,4-~-Polymannuronic acids

Alginate, a colloidal polyuronic acid structural molecule capable of gelation, is used in the preparation of colloidal biodegradable structures such as gels, biofilms, beads, nanoparticles, and microcapsules suitable for applications that range from gel based separation technologies to drug delivery and cell preservation.

Other Notes

A straight-chain, hydrophilic, colloidal, polyuronic acid composed of glucuronic and mannuronic acid residues.
