The effect of structure on the dilute solution properties of branched polysaccharides studied with SEC and AsFlFFF
Cereal arabinoxylans, guar galactomannans, and dextrans produced by lactic acid bacteria (LAB) are a structurally diverse group of branched polysaccharides with nutritional and industrial functions. In this thesis, the effect of the chemical structure on the dilute solution properties of these polysaccharides was investigated using size-exclusion chromatography (SEC) and asymmetric flow field-f...
متن کاملStructure of a water-insoluble D-glucan isolated from a streptococcal organism.
The structure of the extracellular polysaccharide (water-insoluble D-glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, 2,3,4-tri-, 2,4,6-tri, and 2,4-di-O-methyl-D-glucose in the molar ratios of 1.13:3.99:1.00:1.02, indicating that the D-glucan has a branched structure containing (1 le...
متن کاملAlternansucrase acceptor reactions with methyl hexopyranosides.
Alternansucrase (EC 2.4.1.140, sucrose: (1-->6), (1-->3)-alpha-D-glucan 6(3)-alpha-D-glucosyltransferase) is a D-glucansucrase that synthesizes an alternating alpha-(1-->3), (1-->6)-linked D-glucan from sucrose. It also synthesizes oligosaccharides via D-glucopyranosyl transfer to various acceptor sugars. We have studied the acceptor products arising from methyl glycosides as model compounds in...
متن کاملMolecular flexibility of methylcelluloses of differing degree of substitution by combined sedimentation and viscosity analysis.
The flexibility/rigidity of methylcelluloses (MCs) plays an important part in their structure-function relationship and therefore on their commercial applications in the food and biomedical industries. In the present study, two MCs of low degree of substitution (DS) 1.09 and 1.32 and four of high DS (1.80, 1.86, 1.88 and 1.93) were characterised in distilled water in terms of intrinsic viscosit...
متن کاملکالیبراسیون و صحهگذاری دستگاه دیافراگم سل برای اندازهگیری ضریب نفوذ مایعات
In simulation and modeling of mass transfer phenomena and design of separation equipment; and prediction of mass transfer in miscible fuels, it is necessary to have the mass transfer coefficients. In this work, a diaphragm- cell was manufactured to measure the liquid-liquid diffusion coefficient. Then the cell constant was obtained to be 0.188 cm-2 with 0.5 molar solution of potassium chloride ...
