Search for Interstellar Adenine [PDF]
Astrophys Space Sci, 2015, 357, 90, 2015 It is long debated if pre-biotic molecules are indeed present in the interstellar medium. Despite substantial works pointing to their existence, pre-biotic molecules are yet to be discovered with a complete confidence. In this paper, our main aim is to study the chemical evolution of interstellar adenine under various circumstances.

Adenine Abundance in a Collapsing Molecular Cloud [PDF]
arXiv, 2000 A vital ingredient of DNA molecule named adenine may be produced by successive addition of HCN during molecular cloud collapse and star formation. We compute its abundance in a collapsing cloud as a function of the reaction rate and show that in much of ...

Quantum theory of a potential biological magnetic field sensor: radical pair mechanism in flavin adenine dinucleotide biradicals [PDF]
arXivRecent studies in vitro and in vivo suggest that flavin adenine dinucleotide (FAD) on its own might be able to act as a biological magnetic field sensor. Motivated by these observations, in this study, we develop a detailed quantum theoretical model for the radical pair mechanism (RPM) for the flavin adenine biradical within the FAD molecule.

Adenine Nucleotide and Nicotinamide Adenine Dinucleotide Measurements in Plants [PDF]
Current Protocols in Plant Biology, 2020 AbstractAs the principal co‐factors of many metabolic pathways, the measurement of both adenine nucleotides and nicotinamide adenine dinucleotide provides important information about cellular energy metabolism. However, given their rapid and reversible conversion as well as their relatively low concentration ranges, it is difficult to measure these ...

Water dimer driven DNA base superstructure with mismatched hydrogen-bonding [PDF]
J. Am. Chem. Soc. 144, 20227-20231 (2022), 2022 The existence of water dimers in equilibrium water vapor at room temperature and their anomalous properties revealed by recent studies suggest the benchmark role of water dimer in both experiment and theory. However, there has been a limited observation of individual water dimers due to the challenge of water separation and generation at the single ...

Alteration in the molecular structure of the adenine base exposed to gamma irradiation: An ESR study
Open Chemistry, 2023 Adenine polycrystals were obtained from their powder form under effective crystallization conditions by adjustment of the concentration of chemical solutions. The adenine samples were irradiated with a 60Co gamma-ray source at room temperature for 12, 24,

Trypanosoma brucei adenine-phosphoribosyltransferases mediate adenine salvage and aminopurinol susceptibility but not adenine toxicity [PDF]
International Journal for Parasitology: Drugs and Drug Resistance, 2014 African trypanosomes, like all obligate parasitic protozoa, cannot synthesize purines de novo and import purines from their hosts to build nucleic acids. The purine salvage pathways of Trypanosoma brucei being redundant, none of the involved enzymes is likely to be essential.
