1-Deoxy-d-arabinitol
Addition of methyl lithium to d-erythrono-1,4-lactone followed by acid deprotection was shown, by X-ray crystallography, to give 1-de-oxy-d-arabinitol, C(5)H(12)O(4), rather than 1-de-oxy-d-ribitol as the major product. The crystal structure exists as hydrogen-bonded chains of mol-ecules running parallel to the c axis which are further linked together by hydrogen bonds. Each mol-ecule is a dono...
متن کاملThe 5-O-/3-D-Galactofuranosyl-containing Glycopeptide from Penicillium charlesii
Natural abundance carbon 13 nuclear magnetic resonance spectroscopy was used to confirm and extend the structural properties of peptidophosphogalactomannan (pPGM) from Penicillium charlesii. The major resonances for phosphogalactomannan (PGM) and phosphomannan (PM) were assigned. Based on comparison of chemical shifts of carbon 13 resonance signals in phosphogalactomannan with those of galactoc...
متن کاملUrine D-arabinitol/L-arabinitol ratio in diagnosis of invasive candidiasis in newborn infants.
Infants treated in neonatal intensive care units suffer an increased risk for invasive candidiasis, but the diagnosis is sometimes difficult. D-arabinitol is a metabolite of most pathogenic Candida species. An elevated urine D-arabinitol/L-arabinitol (DA/LA) ratio is a sensitive sign of invasive candidiasis in children with cancer, but the method has not been previously evaluated for newborn in...
متن کاملThe versatile enzyme Araf51 allowed efficient synthesis of rare pathogen-related β-D-galactofuranosyl-pyranoside disaccharides.
The preparation of galactofuranosyl-containing disaccharidic parts of natural glycoconjugates was performed according to a chemo-enzymatic synthesis. Our goals were firstly to develop an alternative approach to standard chemical strategies by limiting the number of reaction and purification steps, and secondly to evaluate the scope of the Araf51 biocatalyst to transfer a galactofuranosyl moiety...
متن کاملVacuum Branes in D - Dimensional Static Spacetimes with Spatial Symmetry IO ( D − 2 ) , O ( D − 1 ) or O + ( D −
In this paper, we give a complete classification of vacuum branes, i.e., everywhere umbilical time-like hypersurfaces whose extrinsic curvature is a constant multiple of the induced metric, Kμν = σgμν , in D-dimensional static spacetimes with spatial symmetry G(D−2, K), where G(n,K) is the isometry group of an n-dimensional space with constant sectional curvature K. D ≥ 4 is assumed. It is show...
