Glucose polarimetric measurements

The monosaccharide carriers of Saccharomyces cerevisiae, and also of Kluyveromyces (Saccharomyces) fragilis, appear from polarimetric measurements to have a higher affinity for the a-D anomers of D-glucose, D-mannose, and D-xylose than for the corresponding /3 anomers.178 Intracellularly, a-D-glucopyranose is a slightly better substrate of hexokinase than the /3 anomer.179...

The complexings of D-glucose, D-fructose, and maltose with borate anions have been studied by polarimetric, conductivity, and pH measurements, and circular dichroism methods have been used to investigate the complexing of cuprammonium ions with carbohydrate diols and amino-alcohols. An examination of the c.d. spectra of fifteen methyl 3-acetamido-3,6-dideoxyhexopyranoside derivatives measured in methanol, 2,2,2-trifluoroethanol, and acetonitrile su ests that the amide group is not completely planar and may show chirality. The n it transition of the carboxylic acid carbonyl groups at...
