Deprotonation Dynamics of Guanine Radical Cations† [PDF]
Photochemistry and Photobiology, 2021 AbstractThis review is dedicated to guanine radical cations (G+)· that are precursors to oxidatively generated damage to DNA. (G+)· are unstable in neutral aqueous solution and tend to lose a proton. The deprotonation process has been studied by time‐resolved absorption experiments in which (G+)· radicals are produced either by an electron abstraction ...

Deprotonation from Diphenylsilane with Organosilyllithium Agents [PDF]
Phosphorus, Sulfur, and Silicon and the Related Elements, 2022 In contrast to their carbon analogs, there are only a few reports on deprotonation from silanes. This is because the normal polarization of a Si-H bond is Si(delta+)-H(delta-), while that of a C-H bond is C(delta-)-H(delta+). From a bond orbital perspective, a sigma*CH orbital has greater expansion on hydrogen, while a sigma*SiH orbital has greater ...

Fragmentation of deprotonated N-benzoylpeptides: Formation of deprotonated oxazolones [PDF]
Journal of the American Society for Mass Spectrometry, 2004 The fragmentation reactions of deprotonated N-benzoyl peptides, specifically hippurylglycine, hippurylglyclyclycine, and hippurylphenylalanine (hippuryl = N-benzoylGly) have been studied using MS2 and MS3 experiments as well as deuterium labeling.

Survival of Bacteriophage T4 in Quasi-Pure Ionic Solutions
Viruses, 2023 The preservative qualities of individual ionic compounds impacting the infectivity of T4 virions were elucidated. T4 virions were immersed in quasi-pure ionic solutions prior to the adsorption process, and the plaque forming unit (pfu) values of these ...

Deprotonation-Induced Phase Transitions in the Self-Assembled Structure of Prochiral Carboxyl Derivatives [PDF]
, 2022 Controlling the self-assembly of molecules on solid surfaces is of great importance for creating new functional nanostructures. In this work, phase transitions in the self-assembled structure of the 1,3,5-tris(3-carboxyphenyl)benzene (mTCPB) molecule ...

Relationships between Structure and Antioxidant Capacity and Activity of Glycosylated Flavonols
Foods, 2021 The antioxidant capacity (AC) and antioxidant activity (AA) of three flavonols (FLV), aglycones and their glycosylated derivatives were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)

Predicting the pKa Values of the Deprotonation Equilibria of Benzenonium Carbocations [PDF]
, 2022 The pKa(H) value of the benzenonium carbocation (C6H7+, cy-clohexadienyl cation, Wheland intermediate) is −24.3 [1]. The Hammett’s reaction constant (ρ) value for the deprotonation equilibrium is 14.3 [2].
