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 .
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 , and glycerol and sorbitol .
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.
Table 1: Summarized calculated total sugar results Glucose * Fructose * Sucrose * Total sugar (g/L) (g/L) (g/L) (g/L) Bourbon, American 0.085 0.045 0.110 0.24 ** Whiskey Canadian 0.200 0.145 -- 0.35 Whiskey Flavored 51.0 64.0 -- 105 Rum, Berry Flavored Rum, 80.0 108.0 -- 188 Coconut Flavored 30.0 28.0 108 166 ** Rum, Spicy Irish Whiskey 0.210 0.135 -- 0.35 Rice Wine 22.0 0.6 -- 22.6 * Corrected for dilution ** Note: sucrose is a disaccharide
of glucose and fructose so the total monosaccharide sugar is much higher than shown here.
Encouraged by these results and to compare biological activities of monosaccharide (furanose and pyranose form) benzoates with that of disaccharide
studied heparan sulfate--and dermatan sulfate--derived disaccharides
in DBS among MPS-I, -II, and -III patients (66).
Monosaccharides (glucose and fructose) and disaccharide
(sucrose) were detected in all the extracts.
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 .
