WebbPyranose is a collective term for saccharides that have a chemical structure that includes a six-membered ring consisting of five carbon atoms and one oxygen atom. There may be other carbons external to the ring.

WebbThe bicyclic compound decahydronaphthalene, or bicyclo [4.4.0]decane, has two fused six-mem-bered rings. It exists in cis and trans forms (see Fig. 1.10), as determined by the configurations at the bridgehead carbon atoms. Both cis- and rran -decahydronaphthaiene can be constructed with two chair conformations. WebbBased upon observed 1 S 3 skew boat conformation (or a conformationally very similar 1,4 B boat conformation) in the Michaelis complexes (or in some cases, the product complex) of a number of “β-glucosidases,” along with 4 C 1 chair conformations for the covalent intermediates, a pseudo-rotational itinerary of 1 S 3 → 4 H 3 → 4 C 1 seems likely for the …
