Kinetics and mechanism of degradation of chitosan by combining sonolysis with H2O2/ascorbic acid

This study demonstrated the combined use of sonolysis with the H2O2/ascorbic acid (Vc) redox reaction to degrade chitosan (CS). The influence of operating parameters, such as the initial CS concentration (1-15 mg mL-1), the input power level (15-45% of the total input power), the H2O2 and Vc concentration (10-70 mM) and the pH (3.0-5.0) of the reaction solution, on the molecular weight and degradation kinetics of CS were investigated and optimized. Based on the degradation kinetics, a synergetic effect of sonolysis with H2O2 and Vc on the degradation of CS was observed. Structural analysis by FT-IR and 1H and 13C NMR indicated no significant difference between the chemical structure of chitosan before and after degradation. Moreover, intermolecular hydrogen bonds were broken, and the crystallinity of degraded chitosan decreased. Using the above analysis, CS degradation by the combination of sonolysis with the H2O2/Vc redox reaction was proposed to be due to mechanical effects along with HO attack on the beta-1,4-glucoside linkages of glucosamine units. These results suggest that the sonolysis/H2O2/Vc combined technique is promisingly suitable for large-scale manufacture of chitooligosaccharide.

Insights into neuronal cell metabolism using NMR spectroscopy: Uridyl diphosphate N-acetyl-glucosamine as a unique metabolic marker

Making the switch: Compounds 1 and 2 are used as metabolic markers for NMR detection. When neuronal cells switch to a glycolytic state, an uneven distribution of 13C in the N-acetyl group results, thus giving a mixture of the metabolites 1 and 2. It is therefore possible to monitor flux through different metabolic pathways, such as glycolysis, the tricarboxylic acid cycle, and the hexosamine biosynthetic pathway, using a single molecule.

Novel sequential solid-phase synthesis of N-linked glycopeptides from natural sources

In the present report a practical and versatile procedure for the solid-phase synthesis of N-linked glycopeptides from natural sources has been demonstrated. The approach is based on the mild hydrazinolysis procedure to release N-linked oligosaccharides in their intact unreduced form from the natural glycoproteins, e.g. fetuin and ribonuclease B and subsequent formation of the corresponding glycosylamines. Treatment of the reducing sugars 1-7 with a saturated solution of ammonium hydrogen carbonate in either water or dimethyl sulfoxide (DMSO) gives in almost quantitative yields the glycosylamines 8-14. Coupling of the unprotected glycosylamines 8-14 to the side-chain-activated aspartic acid derivative Fmoc-Asp(ODhbt)-OBut 16 affords the N-glycosylated asparagine derivatives 17-23. Subsequent acetylation of the carbohydrate hydroxy groups and cleavage of the tert-Bu ester by trifluoroacetic acid (TFA) treatment yields the glycosylated N-linked building blocks 31-37. The building blocks 31-37 are then incorporated into the multiple-column peptide-synthesis protocol of the glycopeptide T-cell epitope analogues 40-46 of the mouse haemoglobin-derived decapeptide Hb (67-76), VITAFNEGLK. The decapeptide sequence VITAFNEGLK binds well to the MHC Class II Ek molecule and is non-immunogenic in CBA/J mice. Syntheses of several natural and unnatural glycosylations, e.g. N-acetylglucosamine, N,N?-diacetylchitobiose, glucose, maltotriose, maltoheptose and di- and triantennary complex oligosaccharides on the decapeptide Hb (67-76) affording the N-linked glycopeptides 40-46 are described. The N-linked glycopeptides 40-46 have been fully characterised by 1D- and 2D-1H and 13C NMR spectroscopy and by ES-MS.

Characterization of the single-subunit oligosaccharyltransferase STT3A from Trypanosoma brucei using synthetic peptides and lipid-linked oligosaccharide analogs

The initial transfer of a complex glycan in protein N-glycosylation is catalyzed by oligosaccharyltransferase (OST), which is generally a multisubunit membrane protein complex in the endoplasmic reticulum but a single-subunit enzyme (ssOST) in some protists. To investigate the reaction mechanism of ssOST, we recombinantly expressed, purified and characterized the STT3A protein from Trypanosoma brucei (TbSTT3A). We analyzed the in vitro activity of TbSTT3A by synthesizing fluorescently labeled acceptor peptides as well as lipid-linked oligosaccharide (LLO) analogs containing a chitobiose moiety coupled to oligoprenyl carriers of distinct lengths (C10, C15, C20 and C25) and with different double bond stereochemistry. We found that in addition to proline, charged residues at the +1 position of the sequon inhibited glycan transfer. An acidic residue at the -2 position significantly increased catalytic turnover but was not essential, in contrast to the bacterial OST. While all synthetic LLO analogs were processed by TbSTT3A, the length of the polyprenyl tail, but not the stereochemistry of the double bonds, determined their apparent affinity. We also synthesized phosphonate analogs of the LLOs, which were found to be competitive inhibitors of the reaction, although with lower apparent affinity to TbSTT3A than the active pyrophosphate analogs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 14215-68-0, you can also check out more blogs about14215-68-0

Quantitative estimation of interaction between carbohydrates and concanavalin A by surface plasmon resonance biosensor.

We measured the affinity of more than 20 sugars with concanavalin A (ConA) by an optical biosensor (surface plasmon resonance sensor) using asialofetuin (ASF) as an immobilized binding partner of ConA. We determined kinetic parameters of the effects of sugars on the dissociation of ConA from ASF quantitatively, and the structural requirements of the functional groups of sugars for binding with ConA. We found that the affinity of ConA for sugars is dependent on its conformation induced by interaction with the binding partner. In addition, the results showed that optical biosensor system is well mimics the interaction of ConA with sugars in biomembrane.

Effects of various saccharides on cycloinulo-oligosaccharide fructanotransferase reaction: Production of beta-inulotriosyl-alpha-D- mannopyranoside and 1-O-beta-inulotriosyl-alpha-L-sorbopyranose

The effects of various saccharides on the reaction of cycloinulo- oligosaccharide fructanotransferase with cycloinulohexaose were examined. In addition to beta-D-fructofuranosides and methyl alpha-D-glucopyranoside, D-mannose and L-sorbose were found to be effective acceptors in the reactions, and they enhanced the hydrolytic activity as effectively as methyl alpha-D- glucopyranoside. Hetero-tetrasaccharides were isolated as the major transfer products from both reaction mixtures. The isolates were identified by NMR spectroscopy as beta-inulotriosyl-alpha-D-mannopyranoside and 1-O-beta-inulotriosyl- alpha-L-sorbopyranose. Methyl beta-D-glucopyranoside was slightly effective and methyl alpha-D-mannopyranoside was not effective at all as the acceptor, but these saccharides strongly enhanced the hydrolytic activity. D-Glucosamine inhibited the enzyme activity. (C) 2000 Elsevier Science Ltd.

The rapid and facile synthesis of oxyamine linkers for the preparation of hydrolytically stable glycoconjugates

The synthesis of a number of N-glycosyl-N-alkyl-methoxyamine bifunctional linkers is described. The linkers contain an N-methoxyamine functional group for conjugation to carbohydrates and a terminal group, such as an amine, azide, thiol, or carboxylic acid, for conjugation to the probe of choice. The strategy for the linker synthesis is rapid (3-4 steps) and efficient (51-96% overall yield), and many of the linkers can be synthesized using a three-step one-pot strategy. Moreover, the linkers can be conjugated to glycans in excellent yield and they show excellent stability toward hydrolytic cleavage.
