Reduction of carbohydrates by tritiated borohydride resulted in the production of alditols or glycosides with characteristically divergent specific radioactivities. Simultaneous reduction of individual sugars in the presence of a reference standard,

A simple model system has been developed in which lectin-mediated aggregation of glycoprotein-coated beads can be monitored by following the decrease in light scattering at 650 nm. Aggregation has been characterized with the lectin of Actinomyces vis

The biosynthesis of thymidine diphospho-l-rhamnose from thymidine diphosphoglucose specifically labeled with tritium at carbon 3 has been studied with an enzyme preparation from Escherichia coli B. Under conditions in which conversion to the 6-deoxys

UDP-galactose-4-epimerase and TDP-glucose-oxidoreductase are shown to have analogous reaction mechanisms. TDP-glucose is a substrate for both enzymes, and when labeled with tritium at carbon 4 it displayed an isotope effect for both enzymes. Neither

A decrease in enzymatic activity during the standard assay procedure for UDP-galactose-4-epimerase (EC 5.1.3.2) led to the observation that ADP-ribose-(5) (5-(adenosine-5'-pyrophosphoryl)d-ribose), a degradation product of NAD+, is a strong inhibitor

A method is described for the simple synthesis of D -glucose and D -galactose specifically labeled at C-4 with tritium. Methyl α- D -galactopyranoside (1) was converted into methyl 2,3,6-tri- O -benzoyl-α- D -galactopyranoside ( 2 ). Oxidation of (
