Ulrich Höhle,Erich Peter Klemente 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

As already mentioned in Chapter 5 the carbohydrates have three types of chemically distinct hydroxyl groups: (1) the primary hydroxyl groups which are always exocyclic and (2) two types of secondary hydroxyl groups: endo- and exocyclic hydroxyl groups.

Non-commutative Algebraic Geometryo most important reactions in carbohydrate chemistry. Just as the amino acids are the building blocks for the synthesis of peptides and proteins in living organisms, the monosaccharides are the building blocks for the synthesis of oligosaccharides, polysaccharides, and glycoconjugates (glycoproteins

Masaki Kashiwara,Michèle Vergnes of macrolide antibiotics represents one such difficult problem. They consist of macrocyclic lactone rings with many hydroxylated and methylated chiral carbons. In addition to that the macrocyclic lactones (macrolides) are usually glycosylated with amino sugars.
