Differential scanning calorimetric studies on binding of N-acetyl-D-glucosamine to lysozyme.
Differential scanning calorimetric (DSC) measurements were performed on the thermal denaturation of lysozyme and lysozyme complexed with N-acetyl-D-glucosamine (GlcNAc) at pH 5.00 (acetate buffer), 4.25 and 2.25 (Gly-HCl buffer). DSC data have been analyzed to obtain denaturation temperature T(d), enthalpy of denaturation DeltaH(D), heat capacity of denaturation DeltaC(pd) and cooperativity ind...
متن کاملMetabolism of D-glucosamine and N-acetyl-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 ...
متن کاملThe Crystal Structure of Α-chitin (poly-n-acetyl-d-glucosamine)
A detailed model for the crystal structure of the fibrous polysaccharide chitin is proposed. The structure determination has been carried out by using an optical analogue instrument which proved to be an adequate and rapid tool for the derivation of Fourier transforms, signs of amplitudes and the production of optical Fourier syntheses. The new model of chitin accounts properly for known chemic...
متن کاملSynthesis of oseltamivir and tamiphosphor from N-acetyl-D-glucosamine.
Using N-acetyl-D-glucosamine as a starting material, the anti-influenza drugs oseltamivir and tamiphosphor were synthesized via a pivotal intermediate of aldehyde 8. An intramolecular Horner-Wadsworth-Emmons reaction was utilized to construct the highly functionalized cyclohexene ring. The existing N-acetyl group was transformed into an azido group for the subsequent aziridination, followed by ...
متن کاملIs N-acetyl-d-glucosamine a rigid 4C1 chair?
Understanding microsecond-timescale dynamics is crucial to establish three-dimensional (3D) structure-activity relationships in sugars but has been intractable to experiments and simulations. As a consequence, whether arguably the most important chemical scaffold in glycobiology, N-acetyl-d-glucosamine (GlcNAc), deviates from a rigid (4)C(1) chair is unknown. Here, conformer populations and exc...
