SummaryExperiments on radiation-induced radicals in single crystals of N-acetyl-DL-valine are reported. After X-irradiation at room temperature, free radicals with the structures (CH3)2ĊCH (COOH)NHCOCH3 and (CH3)2ĊCH2COOH were determined by means o

Electron spin resonance measurements were performed in order to investigate the influence of anti-cardiolipin antibodies on cardiolipin-containing liposomes. The physical state of the lipid structures and the alterations caused by the interaction wit

Experiments on the production of free radicals in aqueous solutions of N-methyl and N-acetyl substituted amino acids by UV light are reported. The ESR spectra observed at 77 K show that the bond of the CH3- group of these substances is ruptured to a

Many investigations with electron spin resonance spectroscopy have shown that the spin-lattice interaction of radiation induced free radicals in organic materials is too weak to allow rapid thermal relaxation. Therefore saturation effects can be prod

Es wurde nachgewiesen, das in Glycyl-DL-valin durch Rontgenbestrahlung unter anderen das Radikal gebildet wird. Wird die Substanz anschliesend erwarmt oder dem UV-Licht ausgesetzt, so nimmt die Gesamtradikalkonzentration monoton ab, wahrend die Konze

In der Arbeit wird nachgewiesen, da\ durch Rontgenbestrahlung des N-Acetyl-DL-valins und des Glycyl-DL-valins ebenso wie beim Valin freie Radikale der Form (CH3)2C-R gebildet werden, die sich durch Abtrennen eines H-Atoms ergeben. Au\erdem wird uber

Photolysis of amino acids, peptides and their derivatives leads to the formation of free radicals in these substances. The electron-spin-resonance spectra obtained directly after irradiation at 77 K are not very well resolved. They are recognizable a
