Metabolism 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 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...
متن کاملOral polymeric N-acetyl-D-glucosamine and osteoarthritis.
Many patients with arthritis are using alternative modes of therapy, including nutritional supplements, to treat their arthritis. Most patients never tell their doctors that they are taking alternative medications, and few doctors even ask about such activities. Over-the-counter supplements are expensive and consume large amounts of patients' healthcare dollars. Glucosamine has been widely tout...
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 کاملChemoenzymatic synthesis of N-acetyl-D-neuraminic acid from N-acetyl-D-glucosamine by using the spore surface-displayed N-acetyl-D-neuraminic acid aldolase.
Chemoenzymatic synthesis of N-acetyl-d-neuraminic acid from N-acetyl-d-glucosamine using the spore surface-displayed N-acetyl-d-neuraminic acid aldolase at a high concentration (53.9 g liter(-1)) was achieved in this study. Thus, displaying a target enzyme on the surface of spores might be an alternative for integration of biocatalytic conversion into chemical synthesis.
