The Absolute Best Science Experiment for 2,3,4,6-Tetra-o-acetyl-D-glucopyranose

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Article£¬once mentioned of 10343-06-3, Formula: C14H20O10

The ammonia desorption chemical ionization (HN3-DCI) mass spectra of peracetylated gentiobiose (1) and two isotopically labelled gentiobioses (2 and 3) were examined.Compound 2 is labelled with trideuteroacetyl groups in the non-reducing moiety and 3 with trideuteroacetyl groups in the reducing moiety.It is shown that the + ion is not found direct from + by loss of ketene but appears to be formed by way of a nucleophilic acyl substitution reaction resulting in a neutral species which complexes with NH4+.The disaccharides undergo cleavage at either side of the glycoside oxygen joining the two sugar residues, a process which is accompanied by addition of H or CH3CO to afford neutral species which complex with NH4+.The structure of the ions resulting from H transfer have been inferred by comparison of their mass-analysed ion kinetic energy (MIKE) spectra with MIKE spectra of the + ions compounds of established structure.A ring fragmentation reaction of 1, 2 and 3 is reported.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 10343-06-3 is helpful to your research., Formula: C14H20O10
