The sugar-binding properties of the resulting foldamer, which consists of 18 subunits of seven different types, were tested by incubation with several disaccharides, and the molecule was found to bind detectably only to xylobiose.
For the lipid substrate, LpxK was specific for the glucosamine disaccharide head-group, showing no activity for lipid X, UDP-DAG, or substrates already containing Kdo core oligosaccharide sugars [68].
Furthermore, an estimation of UTI-CS chain length was performed as the ratio between the moles of disaccharides and the moles of UTI, considering 15.974 kDa as UTI molecular weight calculated through ExPASy Compute pI/Mw tool (http://www.expasy.org), according to the sequence reported by Xu et al.
In the meat industry, the sugars added to meat products include sucrose and lactose (disaccharides) [4, 5], honey and rice syrup [1], and glycerol and sorbitol [16].
Serum Levels of glycosaminoglycans and chondroitin sulfate/hyaluronic acid disaccharides as diagnostic markers for liver diseases.
Transglycosylation reaction was performed between a disaccharide oxazoline (Gal-GlcNAc-oxa) as glycosyl donor and GlcNAc-GlcNAc as a glycosyl acceptor at pH 7.0.

Encouraged by these results and to compare biological activities of monosaccharide (furanose and pyranose form) benzoates with that of disaccharide (e.g.
studied heparan sulfate--and dermatan sulfate--derived disaccharides in DBS among MPS-I, -II, and -III patients (66).
Starch is digested through a two step procedure, with alpha amylase breaking it down to disaccharides, before sucrose, isomaltase, maltase, glyco-amylase and lactase break them into digestable mono-saccharides.1
Trehalose, a naturally occurring alpha-linked disaccharide formed by two molecules of glucose, was considered for its well-known protective effects in eukaryotic cells [15].
