The aim of the project was to synthesize α1,2-linked and α1,6-linked dimannosides linked through either an oxygen-atom or a sulphur-atom, and subsequently test the binding properties of the dimannosides to lectins with known specificity towards mannose-containing glycans. Thedimannosides were prepared by a glycosylation reaction using selectively protected monosaccharides containing a thiol or alcohol nucleophilic glycosyl acceptor and a series of different glycosyl donors. The synthetic routes to the different building blocks were designed to efficiently make use of common intermediate compounds to streamline the synthesis. The glycosyl acceptors used forthe synthesis of α1,2-linked as well as α1,6-linked dimannosides were synthesized in few steps and diversified only in the last steps of the synthesis. The glycosyl donors used in the study were synthesized from commercially available starting material in a straightforward and convenientsynthesis in 7 to 8 steps.. ...

Pyranose is a collective term for saccharides that have a chemical structure that includes a six-membered ring consisting of five carbon atoms and one oxygen atom. There may be other carbons external to the ring. The name derives from its similarity to the oxygen heterocycle pyran, but the pyranose ring does not have double bonds. A pyranose in which the anomeric OH at C(l) has been converted into an OR group is called a pyranoside. The pyranose ring is formed by the reaction of the hydroxyl group on carbon 5 (C-5) of a sugar with the aldehyde at carbon 1. This forms an intramolecular hemiacetal. If reaction is between the C-4 hydroxyl and the aldehyde, a furanose is formed instead. The pyranose form is thermodynamically more stable than the furanose form, which can be seen by the distribution of these two cyclic forms in solution. Hermann Emil Fischer won the Nobel Prize in Chemistry (1902) for his work in determining the structure of the D-aldohexoses. However, the linear, free-aldehyde ...
Recent atomic force microscopy stretching measurements of single polysaccharide molecules suggest that their elasticity is governed by force-induced conformational transitions of the pyranose ring. However, the mechanism of these transitions and the mechanics of the pyranose ring are not fully understood. Here we use steered molecular dynamics simulations of the stretching process to unravel the mechanism of forced conformational transitions in 1,6 linked polysaccharides. In contrast to most sugars, 1,6 linked polysaccharides have an extra bond in their inter-residue linkage, C5-C6, around which restricted rotations occur and this additional degree of freedom increases the mechanical complexity of these polymers. By comparing the computational results with the atomic force microscopy data we determine that forced rotations around the C5-C6 bond have a significant and different impact on the elasticity of alpha- and beta-linked polysaccharides. beta-linkages of a polysaccharide pustulan force the ...

Phospholipid patterns of 15 representative strains of the genus Amycolatopsis were recorded by two-dimensional thin-layer chromatography. The structure analysis of the isolated phospholipids was verified by fast atom bombardment-mass spectroscopy. The positive- and negative-ion spectra of the partially purified phospholipid fractions qualitatively reflect their distinctive composition. All strains contained diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylinositol. Two different types of phosphatidylethanolamine and phosphatidylmethylethanolamine were detected, viz., compounds with or without hydroxy fatty acids. These phospholipid patterns underline the integrity of the genus. Fast atom bombardment-mass spectrometry analysis of phospholipid patterns may serve as an aid for differentiation of bacterial species.

Eleven tested anions were able to form adducts with neutral oligosaccharides at low cone voltage in negative ion mode electrospray mass spectrometry. Among them, fluoride and acetate have the abilities to significantly enhance the absolute abundance of [M-H]- for neutral oliogosaccharides. The chloride adduct has the best stability among all the adduct species investigated. For the above three anions, CID of adduct species may be used for structural determination of neutral oligosaccharides. In the presence of F- and Ac-, simultaneous detection of acidic oligosaccharides and neutral oligosaccharides was achieved. The ratio of Cl- : non-Cl-containing product ions obtained in CID spectra of chloride adducts of disaccharides was used to differentiate anomeric configurations of disaccharides. Density functional theory (DFT) was employed to evaluate the optimized structures of chloride adducts of disaccharides. The formation and decomposition of chloride adducts with oligosaccharides of different
Carbohydrate conformation refers to the overall three-dimensional structure adopted by a carbohydrate (saccharide) molecule as a result of the through-bond and through-space physical forces it experiences arising from its molecular structure. The physical forces that dictate the three-dimensional shapes of all molecules-here, of all monosaccharide, oligosaccharide, and polysaccharide molecules-are sometimes summarily captured by such terms as "steric interactions" and "stereoelectronic effects" (see below). Saccharide and other chemical conformations can be reasonably shown using two-dimensional structure representations that follow set conventions; these capture for a trained viewer an understanding of the three-dimensional structure via structure drawings (see organic chemistry article, and "3D Representations" section in molecular geometry article); they are also represented by stereograms on the two dimensional page, and increasingly using 3D display technologies on computer monitors. ...

The primary structure of the major surface glycoconjugate of Leishmania donovani parasites, a lipophosphoglycan, has been further characterized. The repeating PO4-6Galp beta 1-4Man disaccharide units, which are a salient feature of the molecule, are shown to terminate with one of several neutral structures, the most abundant of which is the branched trisaccharide Galp beta 1-4(Manp alpha 1-2)Man. The phosphosaccharide core of lipophosphoglycan, which links the disaccharide repeats to a lipid anchor, contains 2 phosphate residues. One of the core phosphates has previously been localized on O-6 of the galactosyl residue distal to the lipid anchor; the second phosphate is now shown to be on O-6 of the mannosyl residue distal to the anchor and to bear an alpha-linked glucopyranosyl residue. Also, the anomeric configuration of the unusual 3-substituted Galf residue in the phosphosaccharide core is established as beta. The complete structure of the core is thus PO4-6Galp alpha 1-6Galp alpha 1-3Galf ...

A survey was made of the geometry of furanose rings in β-nucleotides and β-nucleosides (as monomers related to nucleic acids) for which structures have been determined by X-ray crystallography. Mean values, and estimated standard deviations from them, were calculated for bond-lengths, bond-angles and conformation-angles. For parameters with values dependent on ring-puckering, separate calculations were made for each ring type. (The rings are puckered in one of three conformations: C-2- or C-3-endo or C-3-exo; C-2-exo has not been observed.) The results were used to compute standard furanose rings with C-2-endo, C-3-endo and C-3-exo conformations for use in nucleic acid molecular model-building. The survey also showed that the only other conformation-angle in nucleotides dependent on the furanose ring conformation corresponds to the relative orientation of the purine (or pyrimidine) base and the ring.. ...

The methyl glycosides of N-acetyl-d-glucosamine (d-GlcNAc) and N-acetyl-d-galactosamine (d-GalNAc) have been used as model glycan analogs to study the effects of lithium cation binding on glycan structure in gas-phase experiments. Infrared multiple photon dissociation (IRMPD) spectra for the two Li+-complexed anomers of methyl-d-GlcNAc revealed a difference of 10 cm−1 between their respective carbonyl stretching band positions. A corresponding 11 cm−1 shift was observed for the two Li+-complexed anomers of methyl-d-GalNAc. Theoretical calculations indicate that the position of the methyl group (α and β, or axial and equatorial, respectively) on carbon 1 of the sugar and its close proximity to the carbonyl of the acetamido group on carbon 2 cause the average orientation of the carbonyl to change in order to minimize steric hindrance. This change in orientation is postulated to be the cause of the observed Cdouble bond; length as m-dashO stretching band shift. The calculations also predict ...

Introduction. Qualitative Tests For Carbohydrates Introduction In this practical experiment there are given , five known carbohydrate solutions. Namely Glucose, Fructose, Xylose, Starch and Sucrose (common table sugar). The first four are what are known as reducing sugars which in solution form either an aldehyde or a ketone. The latter, sucrose, is known as a non-reducing sugar. In addition to these is an unknown carbohydrate solution. There are qualitative food tests that are regularly used to identify the presence of these carbohydrates in foodstuffs. The following are a brief description of these well proven tests for each named carbohydrate. a) The Molisch test for Carbohydrates - the result of this test shows positive where all carbohydrates are present. Monosaccharides (simple one sugar units) give a rapid positive test, whereas Disaccharides (double sugar units) react more slowly. This is due to the Molisch reagent (a-naphthol 95% in ethanol) either dehydrating pentoses (sugars with ...
