The presence of asymmetrical carbons in monosaccharides with different functional groups attached gives rise to optical activity. Monosaccharides are optically active, which means that if polarized light is passed through a solution of these compounds, the plane of light will be rotated to the left ...
(b) The donor ions and molecues which coordinate with the central atom or ion a complex are called ligands The sum of the number of electrons pressent in the central metal ion or atom and those donated by the ligands is called the effective atomic number of the central metal aton and th...

Carbohydrates are diverse bio-macromolecules with highly complex structures that are involved in numerous biological processes. Well-defined carbohydrates obtained by chemical synthesis are essential to the understanding of their functions. However, synt
(Figure 6). The saccharide, β-d-glucuronic acid, is a derivative of β-d-glucose and differs only in the oxidation state of C6; the glucuronic acid contains a C6 carboxylic acid residue. The enantiomer of β-d-glucuronic acid is β-l-glucuronic acid, that is, the mirror image with ...
