Anomeric Effect,s, the conformational mixture of cyclohexanol or its methyl ether contains, at equilibrium, 89% of the conformer with equatorially oriented hydroxyl or methoxy group and 11% of the conformer with axially oriented hydroxyl or methoxy group, indicating clear preference for the equatorial conformer (Fig. 3.1).

Carbohydrate-Based Antibiotics,ibit the life processes of microorganisms. This definition, however, does not include a vast number of chemically modified (semisynthetic) and synthetic antibiotics. Antibiotics are isolated from bacteria, yeast, molds, algae, and lichens, as well as from higher plants.

Anomeric Effect,e axial one, due to fewer nonbonded interactions with other ligands (in this case the C3 and the C5 hydrogen atoms) on the cyclohexane ring . Thus, the conformational mixture of cyclohexanol or its methyl ether contains, at equilibrium, 89% of the conformer with equatorially oriented hydroxyl o
