Additionally, the toxic effects of calystegines may be involved in pathogenesis because they are strong inhibitors of glycosidases, mainly [beta]-glucosidase and a-galactosidase, and it has been suggested that, in vivo, calystegines are likely to disrupt lysosomal function and glycoprotein processing (STEGELMEIER et al., 2008).

When this product was enzymatically degraded by an assay of glycosidase activity, a loss in its chemical proportions of fucose (37.5%), xylose (57.5%) and sulfate (30%) was observed in the electrophoresis, and the further treatment of this same hydrolysate with 0.5 N HCl generated an oligosaccharide presenting an average molecular weight of 4.5 kDa, as revealed by a Sephadex G-25 column.
They include both soluble fibers (pectins, gums, etc.) and insoluble fibers (cellulose, lignin, some hemicelluloses, etc.) [7], Plant-derived fibers and crop derivatives of lignocellulosic composition have been reported to be good biodegradable reinforcing fillers [8-10], Therefore, we hypothesized that the biopolymers of the banana peels might be useful as a filler and reinforcing material [11], During banana ripening, the starch reserve rapidly transforms into sucrose and is further converted into glucose and fructose by the activities of amylase, glycosidase, phosphorylase, sucrose synthase, and invertase [12, 13], Thus, for starch production, it is necessary to process the bananas while they are unripe.
Commensal organisms may synthesize glycosidase, leading to damage of glycocalyx or disaccharidases.
The decrease in the anthocyanin content of the cocoa beans with pod storage might be due to the activities of glycosidase. The degradation of the anthocyanins with roasting might be due to cleavage of the covalent bonds in the anthocyanin molecules during thermal oxidation to form aglycone which then undergo thermal oxidation to form quinones that polymerize with proteins, sugars and other polyphenols [8, 23].

Conclusion: Ultradiluted belladonna could inhibit JE virus infection in CAM, which may be mediated through glycosidase inhibitory role of calystegines present in belladonna.' (23)
The previously available data on 1-thio-[beta]-D-glucopyranosides as glycosidase inhibitors were limited to the derivatives with the following aglycones: phenyl (2a), [K.sub.i] = 1530 [micro]M (Stachybotrys atra) [21]; 4-nitrophenyl, [K.sub.i] = 664 [micro]M (rice) and [K.sub.i] = 95 [micro]M (barley) [22]; benzo-1, 4-quinone, [K.sub.i] = 60 [micro]M (A.
In an animal pharmacokinetic study (18), mogrol and mogroside I were detected in the plasma after oral administration of a mogrosides mixture, suggesting that mogrosides might be digested by glycosidase on the surface of intestinal epithelium cells and transported into the blood stream passively.
