Abstract
Coffee was characterized by proton and carbon nuclear magnetic resonance (NMR) spectroscopy. To identify the coffee components, a detailed and approximately 90% signal assignment was carried out using various two-dimensional NMR spectra and a spiking method, in which authentic compounds were added to the roasted coffee bean extract (RCBE) sample. A total of 24 coffee components, including 5 polysaccharide units, 3 stereoisomers of chlorogenic acids, and 2 stereoisomers of quinic acids, were identified with the NMR spectra of RCBE. On the basis of the signal assignment, state analyses were further launched for the metal ion-citrate complexes and caffeine-chlorogenate complexes. On the basis of the signal integration, the coffee components were successfully quantified. This NMR methodology yielded detailed information on RCBE using only a single observation and provides a systemic approach for the analysis of other complex mixtures.

Abstract
Most Trichoderma reesei cellulases consist of a catalytic and a cellulose binding domain (CBD) joined by a linker. We have used cellohexaose as a model compound for the glucose chain to investigate the interaction between the soluble enzyme and cellulose. The binding of cellohexaose to family I CBDs was studied by NMR spectroscopy. CBDs cause line broadening effects and decreasing T2 relaxation times for certain cellohexaose resonances, whereas there are no effects in the presence of a mutant which binds weakly to cellulose. Yet it remains uncertain how well the soluble cellooligosaccharide mimics the binding of CBD to the cellulose.

Abstract
The hydrolysis of soluble cello-oligosaccharides, with a degree of polymerisation of 4-6, catalysed by cellobiohydrolase II from Trichoderma reesei was studied using 1H-NMR spectroscopy and HPLC. The experimental progress curves were analysed by fitting numerically integrated kinetic equations, which provided cleavage patterns and kinetic constants for each oligosaccharide. This analysis procedure accounts for product inhibition and avoids the initial slope approximation. No glucose was detected at the beginning of the reaction indicating that only the internal glycosidic linkages are attacked. For cellotetraose only the second glycosidic linkage was cleaved. For cellopentaose and cellohexaose the second and the third glycosidic linkage from the non-reducing end were cleaved with approximately equal probability. The degradation rates of these cello-oligosaccharides, 1-12 s-1 at 27 degrees C, are about 10-100 times faster than for the 4-methylumbelliferyl substituted analogs or for collotriose. No intermediate products larger than cellotriose were released. The degradation rate for cellotetraose were higher than its off-rate, which accounts for the processive degradation of cellohexaose. A high cellohexaose/enzyme ratio caused slow reversible inactivation of the enzyme.

Abstract
NMR spectroscopy and HPLC were used to investigate the hydrolysis of cellotriose by cellobiohydrolase II from Trichoderma reesei. Substrate and product concentrations were followed as a function of time. Progress curves were calculated by forward numerical integration of the full kinetic equations and were fitted to the experimental data. Binding and rate constants were obtained from this fit, whereby no initial slope or Michaelis-Menten approximation was used. The progress curves from a single experiment sufficed to produce agreement with the Michaelis-Menten model (eight experiments). The absence of a kinetic isotope effect was proven. The progress-curve analysis showed that a simple degradation model cannot describe the experimental time-courses at substrate concentrations greater than 1 mM. A model containing competitive inhibition from cellobiose as well as non-competitive inhibition from glucose was developed. This four-parameter model accurately reproduces about 1000 experimental data points covering five orders of magnitude in oligosaccharide concentrations. Glucose binding to the enzyme/cellotriose complex retards, in a non-competitive fashion, cellotriose hydrolysis by at least a factor of 30. A structural model for the non-competitive inhibition is discussed. The NMR experiment also produced individual progress curves for the alpha and beta anomers. The beta anomer of cellotriose was degraded 2.5-times faster than the alpha anomer.

Abstract
Galacto-oligosaccharides formed from lactose by the action of some beta-galactosidases were subjected to gel chromatography on Bio-Gel P-2, and the resulting oligosaccharide fractions were converted into pyridylamino (PA) derivatives. Each PA-oligosaccharide fraction, which consisted of several isomers in a given size-class, was then subjected to HPLC on an ODS column. Twenty-one individual galacto-oligosaccharide components were isolated in this way. The structures of most of these compounds, namely six disaccharides, five trisaccharides, two tetrasaccharides, and a pentasaccharide, were determined by 13C-NMR spectroscopy. The results obtained will be useful for the study of the activity of various galacto-oligosaccharides on the growth of Bifidobacterium species.

Abstract
Electrophoretic methods are outlined for the rapid purification and analysis of chondroitin sulphate oligosaccharides on a milligram scale. Isomeric impurities however, exist within specific sized oligosaccharides. Detailed 1H and 13C NMR data for the chondroitin sulphate disaccharides delta 4HexA(1-3)GalNAc6SO3- and delta 4HexA(1-3)GalNAc4SO3- (prepared from shark chondroitin sulphate) are reported. Two-dimensional NMR methods have been employed in the assignment of spectra. Preliminary models of these disaccharides are proposed from molecular mechanics conformational searching and molecular dynamics procedures. This study provides 1H and 13C NMR reference data which will be useful in the investigation of larger chondroitin sulphate oligosaccharides, such as those prepared by the electrophoretic methods mentioned above.

Abstract
In the present paper homo- and hetero-nuclear correlation spectroscopies have been used to assign proton and carbonyl carbon resonances of a number of reduced, peracetylated mono- and oligo-saccharide derivatives. Each of the native structures for which assignments were made represent residues or substructures typically found in N- or O-linked glycans. Using the assigned NMR parameters as a basis, residues contained in parent structures were classified according to their residue type and glycosidic substitution sites using a relatively simple K-Nearest Neighbor pattern recognition approach. The method was able to correctly assign 99% of 77 "test residues" to their correct structural class using the full set of 19 assigned parameters as a basis. Similar correlations made between data and structure were less successful when reduced variable sets selected on the basis of SIMCA optimization were used.

Abstract
The fine structure of a beta-)1----4)-linked glucomannan from Asparagus officinalis has been determined by n.m.r. analysis of the oligosaccharides obtained by acidic and enzymic hydrolyses. Cleavage of the glucomannan with beta-D-mannase from Aspergillus niger and purification by h.p.l.c. gave oligosaccharide fractions that contained Man (mannose), GlcMan (beta-glucopyranosylmannose), Man2, Glc2Man, and Glc3Man as the major components. Simulated digestion of a polymer composed of randomly distributed monomers with the same Glc:Man ratio as glucomannan from A. officinalis led to the same polysaccharides. The random distribution of the monomers of glucomannan from A. officinalis was corroborated by the diffraction diagram of the raw flour, which indicated that the "in situ" glucomannan was amorphous, whereas both cellulose and mannans are crystalline.
