Structural determination of the sialic acid polysaccharide antigens of Neisseria meningitidis serogroups B and C with carbon 13 nuclear magnetic resonance.
The application of 13-C nuclear magnetic resonance to the analysis of some sialic acid-containing meningococcal polysaccharide antigens is described. Complete assignments of the spectra of both theExpand
Structural determination of the polysaccharide antigens of Neisseria meningitidis serogroups Y, W-135, and BO1.
TLDR
Carbon-13 nuclear magnetic resonance (NMR) studies, together with other chemical data, have indicated that the polysaccharide is linked only at C-6 of the D-glucose and C-4 of the sialic acid residues, all the linkages being in the alpha- configuration. Expand
Molecular details of melittin-induced lysis of phospholipid membranes as revealed by deuterium and phosphorus NMR.
TLDR
Findings suggest that melittin is in contact with the acyl chain segments and that its position within the bilayer may depend on the temperature, and that the system returns reversibly to large bilayer structures. Expand
The molecular dynamics of cholesterol in bilayer membranes: A deuterium NMR study
Abstract The 2 H-NMR spectra of selectively deuterated cholesterol, intercalated in egg phosphatidyl-choline, were examined. The orientation of the axis of motional averaging was calculated using theExpand
Spin labels in membranes. Problems in practice.
Effects of replacement of a double bond by a cyclopropane ring in phosphatidylethanolamines: a 2H NMR study of phase transitions and molecular organization.
TLDR
Observations are consistent with the poor packing ability of mixed saturated and cyclopropane-containing chains due to the bulky substituent effect. Expand
Orientational order of unsaturated lipids in the membranes of Acholeplasma laidlawii as observed by 2H-NMR.
TLDR
A striking similarity is shown to exist between the oleate chain conformation of the A. laidlawii membrane and a phospholipid model membrane when the order parameter profiles are plotted at the same reduced temperature. Expand
Biosynthetic pathways in Methanospirillum hungatei as determined by 13C nuclear magnetic resonance.
TLDR
The main metabolic pathways in Methanospirillum hungatei GP1 were followed by using 13C nuclear magnetic resonance, with 13C-labeled acetate and CO2 as carbon sources, indicating that the oxidative or reductive pentose phosphate pathways are not functioning at significant rates. Expand
