Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10.

In eukaryotic protein N-glycosylation, a series of glycosyltransferases catalyse the biosynthesis of a dolichylpyrophosphate-linked oligosaccharide before its transfer onto acceptor proteins1. The final seven steps occur in the lumen of the endoplasmic reticulum (ER) and require dolichylphosphate-activated mannose and glucose as donor substrates2. The responsible enzymes?ALG3, ALG9, ALG12, ALG6, ALG8 and ALG10?are glycosyltransferases of the C-superfamily (GT-Cs), which are loosely defined as containing membrane-spanning helices and processing an isoprenoid-linked carbohydrate donor substrate3,4. Here we present the cryo-electron microscopy structure of yeast ALG6 at 3.0 A resolution, which reveals a previously undescribed transmembrane protein fold. Comparison with reported GT-C structures suggests that GT-C enzymes contain a modular architecture with a conserved module and a variable module, each with distinct functional roles. We used synthetic analogues of dolichylphosphate-linked and dolichylpyrophosphate-linked sugars and enzymatic glycan extension to generate donor and acceptor substrates using purified enzymes of the ALG pathway to recapitulate the activity of ALG6 in vitro. A second cryo-electron microscopy structure of ALG6 bound to an analogue of dolichylphosphate-glucose at 3.9 A resolution revealed the active site of the enzyme. Functional analysis of ALG6 variants identified a catalytic aspartate residue that probably acts as a general base. This residue is conserved in the GT-C superfamily. Our results define the architecture of ER-luminal GT-C enzymes and provide a structural basis for understanding their catalytic mechanisms.

Computed Properties of C13H18O10, Chemical engineers work across a number of sectors, processes differ within each of these areas, are directly involved in the design, development, creation and manufacturing process of chemical products and materials. An article , which mentions 73464-50-3, molecular formula is C13H18O10. The compound – (2R,3R,4S,5S,6S)-2-Hydroxy-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate played an important role in people’s production and life.

A variety of hydroxylic aglycones can be glucuronidated directly with methyl 2,3,4-tri-O-acetylglucopyranuronate (4a), activated with trimethylsilyl trifluoromethanesulfonate (Me3Si-OTf).This reaction provides mostly beta, and sometimes alpha, glucopyranosiduronic acid derivatives (referred to as glucuronides) rapidly and at low temperatures.The epimeric ratio depends on the relative aglycone nucleophilicity vs. its tendency to form a stabilized carbocation by the formal loss of -OH.Glucuronides of various aromatic and aliphatic aglycones as well as those of a number of cyanohydrins were prepared.The characteristic features of the 1H NMR spectra of alpha and beta derivatives which are presented are useful in the assignment of product stereochemistry and determination of epimeric ratios in those reactions where mixtures are obtained.

Sulphonylurea compounds have versatile activities such as antidiabetic, diuretic, herbicide, oncolytic, antimalarial, antifungal and anticancer. The present study describes the design, synthesis and in vivo testing of novel glycosylated aryl sulfonylurea compounds as antihyperglycaemic agents in streptozocine-induced diabetic mice. The rational for the introduction of the glucosamine moiety is to enhance selective drug uptake by pancreatic beta-cells in order to decrease the cardiotoxic side effect commonly associated with sulfonylurea agents. 2-Deoxy-2-(4-chlorophenylsulfonylurea)-D-glucopyranose was found to be the most potent antihyperglycaemic agents among the synthesized compounds in diabetic mice. This investigation indicates the importance of this novel class as potential antihyperglycaemic agents.
