标题:简短而甜蜜:D-葡萄糖到l-葡萄糖和l-葡萄糖醛酸
摘要:获得l型糖和其他稀有糖的稀缺性和昂贵性阻碍了其生物潜能的开发.例如,仅最近才获得的d-聚乙二醇已被认为是一种重要的新食品.在这里,我们从d-葡萄糖中最终合成了99.4%的纯l-葡萄糖,这种方法廉价而又廉价,除了萃取和去除溶剂外,不需要纯化中间体或最终产物.简单的结晶将使纯度提高到> 99.8%.

权利人:THE TRUSTEES OF BOSTON COLLEGE
摘要:Methods for controlled synthesis and chemical recycling of stereoregular polysaccharides via polymerization of biomass-derived anhydrosugars are provided. The anhydrosugars react with an initiator in the presence of a synergy of a catalyst and the initiator providing the polysaccharides with high chain end fidelity and an excellent molecular weight distribution in a controlled manner, which allows for the preparation of polymeric systems with well-defined architectures. The polysaccharides obtained by such methods can be substantially converted to the start monomers in the present of a catalyst and can be used for biomedicine.

标题 :Compounds and methods for analysis and synthesis of saccharide compounds, and method for quantitating saccharide
发明人：YANG WEN-BIN
权利人:ACADEMIA SINICA
摘要:Provided is a method for quantitating a saccharide in a liquid sample. The method comprises incubating the liquid sample with 2,3-naphthalenediamine in the presence of iodine to allow a naphthimidazole group to be linked to the saccharide to obtain a first mixture; obtaining an 1 H-NMR spectrum of the first mixture; and comparing, in said 1 H-NMR spectrum, the intensity or integral of a proton signal corresponding to the saccharide to the intensity or integral of a proton signal corresponding to an internal standard present in the first mixture.

摘要:The present invention generally relates to materials and methods for exploiting glycosyltransferase reversibility for nucleotide diphosphate (NDP) sugar synthesis. The present invention provides engineered glycosyltransferase enzymes characterized by improved reaction reversibility and expanded sugar donor specificity as compared to corresponding non-mutated glycosyltransferase enzymes. Such reagents provide advantageous routes to NDP sugars for subsequent use in a variety of biomedical applications, including enzymatic and chemo-enzymatic glycorandomization.
