The concept of resonance, as defined in classical VB theory, has been submitted to a more rigorous quantum-mechanical analysis, which reveals its intimate connection to the phenomenon of degeneracy. By examining how degeneracy may arise in quantum mechan

Structural properties of modified deoxyadenosine structures in solution. Impact of the gauche and anomeric effects on the furanose conformation A variable temperature high resolution 1H nuclear magnetic resonance study (at 300 or 500 MHz) of the two modified nucleosides 9-(2'-deoxy--D-threo-ribofur...
The presence of a second hydroxyl group in the ortho position, besides the para position, is known to increase the antioxidant activity due to an additional resonance stabilization and formation of o-quinone [3]. The anticarcinogenic properties of CA have attracted the attention of the ...

摘要: A recent article in this Journal ( J. Chem. Educ . 2020 , 97, 1715–1730) contains erroneous isomer numbers of certain sets of organic compounds. We show that correct numbers are produced by constructive enumeration of isomers using a recent molecular structure generator....

In most cases, paralogous subunits are mutually exclusive within SAGA complexes. Individual module subunits are colored according to the code used in Fig. 1.“-”: no ortholog detected. “X”: ortholog exists but is not present in SAGA. #It is unclear whether HAF1 and HAF2 are bona fide...
