Summary: Nutritional deficiency and genetic errors that impair the transport, absorption, and utilization of vitamin B12 (B12) lead to hematological and neurological manifestations. The cblC disease (cobalamin complementation type C) is an autosomal

Perovskite solar cells (PSCs) currently reach high efficiencies, while their insufficient stability remains an obstacle to their technological commercialization. The introduction of hole-transport materials (HTMs) into the device structure is a key a

Besides its use in medicine, vitamin B12 (cobalamin) and its derivatives have found in numerous applications as catalysts. However, studies related to the activation of oxidants via cobalamin are scant. In this work, we showed how the addition of aqu

Hydrogen sulfide (H2S) is a gasotransmitter and the smallest signaling thiol metabolite with important roles in human health. The turnover of H2S in humans is mainly governed by enzymes of sulfur amino acid metabolism and also by the microbiome. As i

Oxidation of sulfide to sulfate is known to consist of several steps. Key intermediates in this process are the so-called small oxoacids of sulfur (SOS)—sulfenic HSOH (hydrogen thioperoxide, oxadisulfane, or sulfur hydride hydroxide) and sulfoxylic

Medicinal effects of hydrophobic derivatives of vitamin [Formula: see text] have been insignificantly investigated primarily due to their low solubility in aqueous solutions. One of the ways to increase their water solubility is the complexation with

A study on the kinetics of the reaction between cyanocobalamin (vitamin B12, CNCbl) and the reduced form of flavin mononucleotide (FMNH2) in weakly acidic, neutral, and slightly alkaline media is performed. It is shown that FMNH2 can reduce CNCbl to

Aquacobalamin binds hydrogen peroxide reversibly to form a cobalt(III) hydroperoxo adduct with a 0.25 mM dissociation constant, as evidenced by UV-vis absorption spectroscopy and corroborated by NMR, Raman spectroscopy, stopped-flow UV-vis measuremen

In this work, we showed that aquacobalamin (H2OCbl) undergoes decomposition in the presence of glucose oxidase and glucose under aerobic conditions at pH 6.3. This process is contributed by two reactions performed by glucose oxidase, i.e. (i) H2OCbl
