Application
Xanthan gum is an anionic polysaccharide composed of a β-(1→4)-D-glucopyranose glucan backbone with side chains of (1→3)-α-D-mannopyranose-(2→1)-β-D-glucuronic acid-(4→1)-β-D-mannopyranose on alternating residues. Approximately half of the terminal mannose residues are 4,6-pyruvated while most of the inner mannose residues are 6-acetylated. Its properties make it a useful matrix component for drug delivery systems. It forms stable drug suspensions in aqueous media and soft gels with locust bean gum or guar gum. Xanthan gum mimics the texture of lipids and is used as a control in experiments where signaling pathways initiated by consumption of lipid-containing reagents are investigated in mice.
Autres remarques

Differently modified xanthans, varying in degree of acetylation and/or pyruvylation were incubated with the experimental cellulase mixture C1-G1 from Myceliophthora thermophila C1. The ionic strength and/or temperature of the xanthan solutions were varied, to obtain different xanthan conformations. The exact

We report the development of halloysite nanotubes (HNTs)/carboxylated-cellulose nanocrystals (cCNCs) - reinforced and ionically-crosslinked k-carrageenan (k-CG)/xanthan gum (XG) hydrogels. In this study, cCNCs were extracted from microcrystalline cellulose using ammonium persulfate and exhibit 'spindle-like' nanocrystals with approximate diameter of 15-30 nm
