Antivitamins represent a broad class of compounds that counteract the essential effects of
vitamins. The symptoms triggered by such antinutritional factors resemble those of vitamin …

The marvel of X-ray crystallography is the beauty and precision of the atomic structures
deduced from diffraction patterns. Since these patterns record only amplitudes, phases for …

Substitution of CoIII-bound water by cyanide allows the rapid colorimetric detection of
micromolar amounts of cyanide with cobalt corrinoids. Negatively charged side chains at the …

Metal complexes of tetrapyrrolic macrocycles play a central role in Earth's life because of
their implications in a variety of enzymatic systems.* 1 Their ability to carry out reactions …

One of the most characteristic and perhaps one of the most thoroughly studied chemical
properties of cobalamins is the so-called base-on-base-off reaction in which the axially co …

Additional parameters for the amber force field have been developed for the molecular
mechanics modeling of the cobalt corrinoids. Parameter development was based on a …
