In subject area: Chemistry Isomerism refers to the ability to alter the behavior of biomolecules without changing their composition by modifying their molecular topology, allowing for different organizational and functional properties. AI generated definition based on: Current Opinion in Colloid & Interface...
Optical Isomerism in Drugs Camille G.Wermuth, inThe Practice of Medicinal Chemistry (Fourth Edition), 2015 IIntroduction This chapter is concerned with bioactive compounds bearing on their skeleton one or more asymmetric carbon atom(s). For such compounds the term “configuration” defines the implan...

Indeed, it was some years before this “first” case of nuclear isomerism was accepted as being correct. The word “isomer” itself seems to have been used in the literature, for the first time in the nuclear context, by Gamow in 1934 [9], after the discovery of neutrons by Chadwick ...
The two main types of stereoisomerism are optical isomerism (tacticity) and cis–trans isomerism. The optical isomerism is also related to macromolecular chirality (enantiomerism, see Figure 8 and Section 1.02.1.8). Sign in to download full-size image Figure 8. (a) Chiral poly-l-alanine ...

OPTICAL ISOMERISM IN DRUGS Camille G. Wermuth, in The Practice of Medicinal Chemistry (Second Edition), 2003 D Isomer effects on excretion The kinetics of excretion are a direct consequence of the kinetics of metabolic transformations. The faster a drug is metabolized, the faster its elimination ...
Essential oil components often exhibit optical isomerism (where the two isomers are mirror images of each other). For example, (+)-carvone isolated from caraway oil has a caraway-like odour and (−)-carvone isolated from spearmint oil has a spearmint-like odour. Pharmacodynamics Aromatherapy ...
A flower is isomerous if all whorls have the same number of members or the number in one whorl is a multiple of that of another. A flower is heteromerous if the number of members in one or more whorls differs from that of the remaining whorls, and is not a multiple of the number ...
A It can be difficult at first to classify carbohydrates by their chirality centers. This is because there can be many chirality centers in the carbon backbone. This concept is simply an extension of stereoisomerism fromChapter 3. We now take a look at what this looks like for carbohydrate...
