[R]esonance is not an intrinsic property of a molecule that is described as a resonance hybrid, but is instead something deliberately added by the chemist or physicist who is talking about the molecule. In anthropomorphic terms, I might say that the molecule does not know about the resonance...
I remember sitting near my dear friend Takashi Yonetani in the grand Auditorium full of biochemists lissening at Max illustrating the 3D structure of oxy and deoxy hemoglobin, the location of the salt bridges constraining the T-state and the active site trigger. A stellar talk. In the ...
\Viihler contnbuted to the Journal of the German Chemical Society in r87 5, contains a delight- ful sketch of the personal relations in which the great German chemist stood to his illustrious master; and Dr. Hofmann's account of Wohler's life and works, published in the same journal for...

Hence, to avoid this cryptic situation, the direct (hetero)arylation (DHA) appears to be method of choice, from the chemist point of view, to afford the next generation of π-conjugated materials [8–15]. The latter indeed offers several practical advantages such as (i) a simplified and ...

and those that are isolated in an active functional form often do not retain activity for long despite all the efforts, up to the point that the biochemists work in refrigerated cold rooms at 4 C in a quest to slow down protein inactivation by keeping their preparations cold at all times...
The fundamentals of this paper were illustrated by Perutz during the opening Conference of the VIII International Congress of Biochemistry in Interlaken (CH). I remember sitting near my dear friend Takashi Yonetani in the grand Auditorium full of biochemists lissening at Max illustrating the 3D st...
6. It is common to draw the enantiomers of the amino acids in the so-called Fischer projection, named after Emil Fischer, the great German chemist. Here the COOH and CH3 groups of one of the enantiomers are aligned vertically with the COOH group at the top. This forces the hydrogen and...
"Life is about redox chemisty" leans, of course, on Albert Szent-Györgyi's famous but extremely difficult-to-pinpoint quote" Life is nothing but an electron looking for a place to rest". Is this view more useful than Schrödingers's negentropy? It depends on the meaning of 'useful...
