Optical isomers of chloropropanediols: mechanisms of their formation and decomposition in protein hydrolysates

Czech Journal of Food Sciences, 2002
Protein hydrolysates produced by hydrochloric acid hydrolysis were analysed for 3-chloropropane-1,2-diol and its enantiomers. It was found that (R)-3-chloropropane-1,2-diol and (S)-3-chloropropane-1,2-diol were present in the hydrolysates in equimolar ...

Helical Single Crystals of Porous Hydrogen‐Bonded Organic Frameworks as a Candidate for Morphologically Functional Organic Materials

Angewandte Chemie, EarlyView.
Helical‐shaped crystals of a hydrogen‐bonded organic framework (HOF) with permanent porosity have been developed. The helical HOF shows expansion and contraction, respectively, upon desorption and adsorption of solvents. Moreover, doping of additive molecules can modulate the photophysical properties and morphology of the helical HOF, showing the ...

An X‑Shaped Chiral Non‑Fullerene n‐Type Semiconductor: Application in Perovskite Solar Cells and Chirality‑Induced Spin Selectivity

Angewandte Chemie, EarlyView.
A highly electron‑accepting derivative of cyclobisbiphenylenecarbonyl (CBBC‐TIC) is reported. CBBC‐TIC functions as an electron‐transport layer for perovskite solar cells, achieving a power conversion efficiency of 20.6%. Furthermore, the enantiomers of CBBC‐TIC exhibited spin‐selective electron transport with high enantiospecific magnetic conductance ...

Enantioselective Separation of 4,8-DHT and Phytotoxicity of the Enantiomers on Various Plant Species

Molecules, 2016
As a candidate for bioherbicide, 4,8-dihydroxy-1-tetralone (4,8-DHT) was isolated from Caryospora callicarpa epicarp and its two enantiomers, S-(+)-isosclerone and R-(−)-regiolone, were separated by chiral high-performance liquid chromatography (HPLC) on

R-flurbiprofen reduces neuropathic pain in rodents by restoring endogenous cannabinoids [PDF]

, 2010
Background: R-flurbiprofen, one of the enantiomers of flurbiprofen racemate, is inactive with respect to cyclooxygenase inhibition, but shows analgesic properties without relevant toxicity. Its mode of action is still unclear.

The effect of amino acid enantiomers on activity of selected enzymes in soil

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
This work was aimed to test the effect of selected amino acid enantiomers on activity of casein-protease and acid phosphomonoesterase in soil. Casein-protease was selected due to its key role in nitrogen mineralization and acid phosphomonoesterase due to

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
