Biochemistry. Dec 25; 29(51) Limonene is a very abundant monocyclic monoterpene that is found in more than plant species. Other studies (see references cited in van der Werf and others, ) also have shown that enzymatically catalyzed β-oxidation of the alicyclic ring of limonene takes place.

Ab initio molecular orbital theory with the minimal STO-3G basis set is used to study the conformations, stabilities, and charge distributions of 35 monosubstituted benzenes. The molecular structural conformations of GSH depend on the surrounding micro-environment, and it has been experimentally evaluated using NMR and Raman spectroscopic techniques as well as by molecular dynamics simulation studies.

The converging report indicates that GSH exists mainly in two major conformations, i.e., “extended” and Cited by: 7. Research Interests Publications.

Alicyclic chemistry is a fundamentally important area of chemistry. It exemplifies the concepts of bonded and non-bonded interactions of atoms, and the ideas of molecular strain and their impact on the stability and reactivity of a range of molecular types.

This book aims to present the experimental basis for these concepts. A survey of alicyclic chemistry must, however, also discuss the more.
