“…The derivative is a N,Ocarboxymethylchitosan, with a degree of substitution (DS) of 0.9 according to the data from the supplier. DS can be determined by the molar ratio of carboxymethyl acid groups to monosaccharide units, as follows: DS abs =mol of -CH 2 COOH groups/mol of monosaccharide unit [13]. In Fig.…”

“…12 Independent of the origin, CG is mainly composed of three types of galactan units within the core, linked by C-1 and C-3, C-1 and C-6 and C-1, C-3 and C-6. 10,11 Modifications have been carried out to cashew gum in order to increase its ionic charge in the carboxylate group, such as carboxymethylation 13 and oxidation with TEMPO reagent. 14 An overcharged new polysaccharide (carboxymethylated) has been used in the preparation and characterization of polyelectrolyte complex nanoparticles with chitosan to identify their application as a drug delivery system.…”

“…A goma do chichá contém galactose, ramnose e xilose e elevado percentual de ácido urônico (42,2%), além de ser parcialmente acetilada (10,7%) 8 . A adição de sais às soluções de goma e a presença do grupo acetil influenciam diretamente na viscosidade da mesma 9 .…”
