✦ Synopsis

The reaction of 2-amino-2-deoxy-D-glucose with lysine in water under simulated physiological conditions gave several browning products, with characteristic optical (lambda max 340 nm) and fluorescent properties (emission at 430 nm for excitation at 362 nm). The major product was isolated and characterized by mass spectrometry and n.m.r. spectroscopy as 2,5-bis(tetrahydroxybutyl)pyrazine derived by the condensation of two molecules of 2-amino-2-deoxy-D-glucose.

We isolated stable mutants from Trichosporon adeninovorans resistant to 2-deoxy-~-glucose. All mutants were altered in the C-catabolite repression and produced different amounts of glucoamylase and 8-glucosidase when grown on several carbon sources. In addition to the C-catabolite derepression of th

The incorporation of 2-amino-Zdeoxy-D-glucose from precursor 2-amino-2deoxy-D-galactose into liver glycogen has been shown to be a metabolically inhomogenous process after starvation. The protein-to-polysaccharide ratio is also heterogeneous with respect to molecular size, and enhanced overall as c
