Living organisms sense and respond to light, a crucial environmental factor, using
photoreceptors, which rely on bound chromophores such as retinal, flavins, or linear …

Biologically active derivatives of vitamin B12 are organometallic cobalt-corrinoid complexes
crucial for the healthy function of humans, animals and microbes. Their role as cofactors to …

Femtosecond time-resolved X-ray absorption (XANES) at the Co K-edge, X-ray emission
(XES) in the Co Kβ and valence-to-core regions, and broadband UV–vis transient …

Ultrafast, polarization-selective time-resolved X-ray absorption near-edge structure (XANES)
was used to characterize the photochemistry of vitamin B12, cyanocobalamin (CNCbl), in …

We have used transient absorption spectroscopy in the UV–visible and X-ray regions to
characterize the excited state of CarH, a protein photoreceptor that uses a form of B12 …

This Perspective Article highlights recent theoretical developments, and summarizes the
current understanding of the photolytic properties of cobalamins from a computational point …

The biologically active forms of vitamin B 12, methylcobalamin (MeCbl) and
adenosylcobalamin (AdoCbl), are important cofactors in a variety of enzymatic processes. In …

Cobalamins are of widespread importance in biology. Both of the cofactors essential for
human metabolism, the organocobalamins coenzyme B12 and methylcobalamin, are highly …

Limited studies have reported on the effect of non-thermal processing technologies on
vitamin B 12, an essential vitamin that does not occur in many plant based foods. In this …

Ultrafast time-resolved spectroscopy was used to study the photochemistry of
hydroxocobalamin (HOCbl) and aquocobalamin (H2OCbl+) in solution. Spectroscopic …
