Investigation of the chirality of enantiomers through information theory [PDF]

, 2009
In this work [1] we probed the Kullback-Leibler information entropy as a chirality measure, as an extension of previous studies on molecular quantum similarity evaluated for different enantiomers (enantiomers possessing two asymmetric centra in [2], with

Chirality at the Nanoparticle Surface: Functionalization and Applications

Applied Sciences, 2020
Chiral molecules, such as amino acids and carbohydrates, are the building blocks of nature. As a consequence, most natural supramolecular structures, such as enzymes and receptors, are able to distinguish among different orientations in space of ...

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 ...
