  resource-based processes. Tungsten-based catalysts (e.g., WO3) are efficient for selectively cleaving C-C bonds of sugars to C2,3 oxygenate intermediates (e.g., glycolaldehyde) that can serve as platform molecules with high viability and versatility in the synthesis of various chemicals. Such C-C bond cleavage follows a mechanism distinct from the classical retro-aldol condensation. Kinetic, isotope 13C-labeling

  将天然存在的糖（地球上最丰富的生物质资源）转化为燃料和化学品，为当前基于化石资源的工艺提供了可持续且碳中性的替代方案。钨基催化剂（例如WO3）可有效选择性地将糖的CC键裂解为C2,3含氧化合物中间体（例如乙醇醛），该中间体可作为平台分子，在各种化学品的合成中具有高活力和多功能性。这种CC键断裂遵循与经典逆醛醇缩合不同的机制。动力学、同位素 13C 标记、光谱研究和理论计算表明，该反应通过作为 WO3 关键中间体的表面三齿复合物进行，该复合物是通过螯合糖的 α- 和 β- 羟基与羰基形成的，两个相邻的钨原子 (WOW) 有助于 β-CC 键断裂。这种机制提供了对糖化学的深入了解，并能够合理设计催化位点和反应途径，以实现糖基原料的有效利用。

  Described is a method for analysing the metabolites of a biological sample which comprises quantitatively determining one or more metabolites in said sample in a way that said quantitative determination resolves isotopic mass differences within one metabolite, said method being characterized in that the sample comprises or is derived from a cell which has been maintained under conditions allowing the uptake of an isotopically labeled metabolizable compound so that the metabolites in said cell are saturated with the isotope with which said metabolizable compound is labeled. This method may further comprise, prior to quantitative determining the metabolites, combining the biological sample (i.e. the first biological sample) with a second biological sample in which the metabolites are not isotopically labeled or are isotopically labeled differently from the first biological sample; and determining in said biological samples the relative quantity of metabolites which differ by their isotopical label. Furthermore described is a set of isotopically labeled metabolites obtainable by applying this method, as well as kits facilitating the application of this method and corresponding uses.
