The techniques used to detect and quantify cyanocobalamin (vitamin B12) vary considerably in terms of detection sensitivity, from the most sensitive, based on radioisotopes and mass spectrometry (MS) with limits of detection (LOD) in fg mL1, to fluorescence (FL) and surfac...
Hydroxocobalamin combines with cyanide in an equimolar ratio to formcyanocobalamin[79]. Cyanocobalamin is also known as vitamin B-12; it is nontoxic and renally eliminated. View article Significance of elevated cobalamin (vitamin B12) levels in blood ...
41.4B. It has a molecular formula of C63H91CON13O14P with a molecular weight of 1344.8 g/mol (The European Food Safety Authority, 2008). This form of vitamin is one of two active coenzymes in the body. It is specifically the cofactor vitamin B12 form required by 5-methyTHF to ...
