NMR showed that EPS was composed of alpha-glycosidic bond (85.0-6.0 ppm) and beta-glycosidic bonds (84.5-5.0 ppm). The peaks near at 1644 cm -1 and 590 cm-1 correspond to uronic acid and sulphate groups, respectively. CEPS had the highest ability to scavenge DPPH (58.98 +/- 1.54%)...
The binding sites on the main and branched chains of fucoidan polysaccharides have numerous types of glycosidic bonds and complex structures. For example, the fucoidan from Sargassum duplicatum has a large number of 1,3-linked 2,4-disulfated fucose residues with branching points located at C2, ...
of a number of glucose molecules joined together by glycosidic bonds (i.e., amylose and amylopectin) (Ismail et al.,2013; Tharanathan,2005). Amylose is a linear polysaccharide with α-1,4-glycosidic bonds, which typically constitutes 15–20% (0–70% in particular cases) of starch. ...
linkage, such as the β-O-4 unit. In addition, H-LS degraded more rapidly than Na-LS because acidic functional groups, notably sulfonic acid, can act as catalysts to facilitate degradation reactions, such as the decomposition of hemicellulose and the breakdown of chemical bonds in lignin ...
There are considerable differences between bacterial and mammalian glycans. In contrast to most eukaryotic carbohydrates, bacterial glycans are often composed of repeating units with diverse functions ranging from structural reinforcement to adhesion, co
