Polysaccharides monosaccharides

Very useful manual for analysis of all types of sugar-containing molecules—monosaccharides, polysaccharides and glycosamino-glycans, glycoproteins, proteoglycans, and glycolipids.

Adsorption can be used to differentiate between free dissolved monomeric phenols and monomeric carbohydrates. Muenster (1982) showed that the sum of both monomeric substance classes in Lake Plussee water comprised between 3 and 10% of the total DOC concentration depending on the resin used. Perdue and co-workers (Lytle and Perdue, 1981 Sweet and Perdue, 1982) utilized Amerlite XAD-7 resin to adsorb humic substances and determined free dissolved amino acids and humic-acid-associated amino acids, as well as monosaccharides, polysaccharides, and humic-bound saccharides in the Williamson river system (Oregon). As a mean, less than 4% of the dissolved amino acids occurred in free dissolved form, and only 2.6% of the total carbohydrates were monosaccharides. This observation as well as some ecophysiological implications are described more extensively in a later section. 

Of immense biological interest is the interaction of metal ions with monosaccharides, polysaccharides, and glycoproteins. To this end, the interaction of Gd and Mn " " with methyl a- and ) -D-galactopyranoside (13 and 14),... 

Polysaccharides are polymers of monosaccharides. Polysaccharides are formed by linking many monosaccharides together with an oxygen bridge. 

Polysaccharides are polymers of monosaccharide units. The monomeric units of a polysaccharide are usually all the same (called homopolysaccharides), though there are exceptions (called heteropolysaccharides). In some cases, the monomeric units are modified monosaccharides. Polysaccharides differ in the composition of the monomeric unit, the linkages between them, and the ways in which branches from the chains occur. Common polymers, their monomeric units, and linkages/ branches are shown below ... 

Lectins are proteins that reversibly bind monosaccharides, polysaccharides, or sugar residues from glycoproteins. Lectins differ in their sugar specificity, their construction, and in the cofactors necessary for binding the sugar. Lectins that are covalently coupled to matrices are popular affinity materials and are available in retail (Table 5.5). Their specificity is shown in Table 9.1. 

Monosaccharides, polysaccharides, amino acids, polypeptides, proteins, and depsides were investigated extensively by Fischer. His monomers related to the polysaccharides included formaldehyde, hydroxyacetaldehyde, several other polyhydroxyaldehydes and the sugars. Fischer s monomers related to... 

The use of C n.m.r. spectroscopy in elucidating the structures of monosaccharides, polysaccharides, nucleosides, and nucleotides has been reviewed. A study of the tautomerism of formycin and related compounds using C n.m.r. spectroscopy is noted in Chapter 21. ...
