Temperature dependencies of amide1H- and15N-chemical shifts in hyaluronan oligosaccharides
Temperature coefficients (Deltadelta/DeltaT) of amide chemical shifts of N-acetylglucosamine residues have been measured in a range of oligosaccharides of the important vertebrate polysaccharide hyaluronan. Odd- and even-numbered oligosaccharides with glucuronic acid, A-4,5-unsaturated glucuronic acid and N-acetylglucosamine at the termini were investigated. All amide proton temperature coefficients were only slightly less negative (-6.9 to -9.1 ppb/C) than those of amide protons in free exchange with water (?-11 ppb/C), indicating an absence of persistent intramolecular hydrogen bonds. With the exception of amide groups in reducing-terminal N-acetylglucosamine rings, all amide proton environments have the same temperature coefficient (-6.9 ppb/C), irrespective of differences in amide group chemical shifts and 3JHH coupling constants, i.e. they do not sense subtle differences in orientation of the amide group. Amide nitrogen temperature coefficients report the same phenomena but with greater sensitivity. These data provide a set of reference values for temperature coefficients measured in other carbohydrates with acetamido sugars. Copyright
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14215-68-0 is helpful to your research., Related Products of 14215-68-0
