4 Tellimagrandin 1: 214,273 2,3-di-0-galloyl-4,6-0- HHDP-[beta]-d- glucopyranose
There are three natural cyclodextrins ([alpha]-, ([beta]-, and [gamma]-) comprised of six, seven, and eight glucopyranose
units, respectively, that have limited solubility in water.
carbohydrate products of dcgraded/microbial SOM are probably those that plot in the NW quadrant: furans (4-acetylfuran, 3/2furaldehyde and 5-methyl-2-furaldehyde), glucopyranose
, which is a microbial marker (Nierop et al.
Addition of [beta]-cyclodextrin, a cyclic molecule having seven [alpha]-l,4-linked glucopyranose
units, was one of the approaches utilized in our attempts to probe intermo-lecular interactions related to the shear-thickening mechanism observed in aqueous mixtures of L-100 and X-45.
Beta-cyclodextrin (BCD) is a cyclic oligosaccharide that consists of seven glucopyranose
units, linked by alpha 1-4 glycoside linkages.
Cyclodextrins are cyclic polysaccharides made up of common, naturallyoccurring D-(+)- glucopyranose
units joined by [alpha]-(1,4) linkages.
61 1,2,6-tri-O-galloylglucose Salminen etal.
In pulp, cellulose has a strong interaction with water due to three hydroxyl groups attached to the glucopyranose
ring [11, 20-22].
One of the most interesting substance is chitosan, chitosan that attract the attention of the scientist in last few years this because of its special properties including biodegradability, biocompatibility and non toxicity, it was a natural polysaccharide composed of linear poly [beta]-(1-4)-2 deoxy-D glucopyranose
These molecules, with the groups attached by hydrolytically stable ether linkages, are based on cyclic oligosaccharides of seven glucopyranose
units with alpha 1-4 glycoside linkages.
Cyclodextrins have six, seven or eight glucopyranose
rings, known as alpha, beta and gamma cyclodextrins respectively.
Three types of native CD; [alpha]-CD, [beta]-CD, and [gamma]-CD having six, seven, and eight glucopyranose
units, respectively, were used for a comparative study.
