Crystallization of enantiomers

, 2006
Pure enantiomers are of large interest for several industries. Chemical synthesis is frequently not selective and provides racemic mixtures causing a large interest in efficient separation processes.

Theoretical Investigation on H2O2-Ng (He, Ne, Ar, Kr, Xe, and Rn) Complexes Suitable for Stereodynamics: Interactions and Thermal Chiral Rate Consequences

Frontiers in Chemistry, 2019
Although molecular collisions of noble gases (Ng) can be theoretically used to distinguish between the enantiomers of hydrogen peroxide - H2O2 (HP), little is known about the effects of HP-Ng interactions on the chiral rate. In this work, the chiral rate

General Anesthetics: Aspects of Chirality, Pharmacodynamics, and Pharmacokinetics

Pharmaceuticals
The introduction of general anesthetics in the mid-19th century is considered one of the greatest contributions to medical practice. It was the first time that complicated surgical interventions became feasible, without putting an excessive strain on the

Microbial consumption dynamics of racemic amino acids (L-enantiomers: open symbol; D-enantiomers: filled symbol) following addition to soils.

, 2014
The rapid absorption of D-enantiomers is presumably by bacteria, which possess amino acid racemases and can turn D-enantiomers into L-forms.

Molecularly imprinted monolithic stationary phases for liquid chromatographic separation of enantiomers and diastereomers

, 2003
The method for preparation of molecularly imprinted monolithic stationary phase has been improved to achieve liquid chromatographic separation of enantiomers and diastereomers. By adopting low polar porogenic solvents of toluene and dodecanol and optimal

Stochastic Detection of Enantiomers

, 2016
The rapid quantification of the enantiomers of small chiral molecules is very important, notably in pharmacology. Here, we show that the enantiomers of drug molecules can be distinguished by stochastic sensing, a single-molecule detection technique.

Ratio of l-(+)- and d-(−)-Lactic Acids Produced by Enterococcus faecalis Changes Depending on the Culture pH

Microbiology Research
Enterococcus faecalis (E. faecalis) has been associated with the specific production of l-(+)-lactic acid. However, in this study, d-(−)-lactic acid production by E. faecalis was observed under specific pH conditions. E.
