Studies on D-Glucosamine Derivatives. IV. D-Glucosamine Diethylmercaptal Derivatives.

The shape of D-glucosamine.

The bioactive amino monosaccharide D-glucosamine has been generated in the gas phase via laser ablation of D-glucosamine hydrochloride. Three cyclic α-(4)C1 pyranose forms have been identified using Fourier transform microwave techniques. Stereoelectronic hyperconjugative forces - essentially linked with the anomeric or gauche effect - and cooperative OH···O, OH···N and NH···O chains, extended ...

Metabolism of D-Glucosamine and kketyl-D- glucosamine in the Intact Rat*

It has been demonstrated that n-glucosamine and N-acetyln-glucosamine are metabolized in animal tissues to n-fructose via phosphorylated intermediates (14). It has also been shown that n-glucose is converted to n-glucosamine and incorporated into glycoproteins and mucopolysaccharides (Pll), probably through formation of uridine diphosphate derivatives as intermediates (4). Little work has been ...

D-Glucosamine Promotes Transfection Efficiency during Electroporation

D-Glucosamine is a useful medicament in various fields of medicine and dentistry. With respect to stability of the cell membrane, it has been reported that bradykinin-induced nociceptive responses are significantly suppressed by the direct application of D-glucosamine. Electroporation is usually used to effectively introduce foreign genes into tissue culture cells. Buffers for electroporation w...
