Tartaric acid gyration tensor components from charge-density distribution

Biscationic Tartaric Acid-Based Amphiphiles: Charge Location Impacts Antimicrobial Activity.

Cationic amphiphiles have received increasing attention as antimicrobials given their unique ability to disrupt bacteria cell membranes. While extensive research has demonstrated that amphiphiles' hydrophobic-to-charge ratio significantly modulates antibacterial activity, less work has focused on elucidating the specific impact of charge location on amphiphile bioactivity. In this study, two se...

Charge density of light exotic nuclei and ρNN tensor coupling

We use a relativistic mean field model to study the charge density distributions of exotic oxygen isotopes. Nonlinear isoscalar-isovector terms which are not constrained by the present data are considered and the ρNN tensor coupling that does not affect the symmetry energy in the mean field model is included. Strong correlations between the neutron radius of Pb and the charge radius of O are fo...

Significance of urinary tartaric acid.

p-Coumaroyl-meso-tartaric acid from spinach chloroplast preparations.

In a recent publication1 we reported on the isolation and identification of flavonoids and cinnamic acid derivatives from spinach chloroplast preparations. These cinnamic acid derivatives and flavonoids are obtained as low molecular fractions I and II from a water extract — called S^eth — from ether treated lyophilized chloroplasts, which is assumed to contain functional components of the photo...

Syntheses of C2-symmetric vicinal diamines derived from tartaric acid

C2-symmetric vicinal diamines 3b–f, derived from L-tartaric acid, with increasingly bulky terminal ether functionalities were prepared using two distinct sequences. Diamines 3b,c were obtained from the corresponding vicinal diols 4b,c, while diamines 3d–f were generated from dihydroxydiazide 7 via deprotection–reprotection strategies. © 1999 Elsevier Science Ltd.
