A new reversed-phase chromatographic method is described for the separation and quantification of thiamine (T), thiamine monophosphate (TMP) and diphosphate (TDP) in rat tissues. Sample extraction with perchloric acid (HClO(4)) was found more suitable than extraction with trichloroacetic acid (TCA)

The biosynthesis of thiamine in Escherichia coli requires the formation of an intermediate thiazole from tyrosine, 1-deoxy-d-xylulose-5-phosphate (Dxp), and cysteine using at least six structural proteins, ThiFSGH, IscS, and ThiI. We describe for the first time the reconstitution of thiazole

Vitamin B1, which consists of the vitamers thiamin and its phosphorylated derivatives, is an essential micronutrient for all living organisms because it is required as a metabolic cofactor in several enzymatic reactions. Genetic diversity of vitamin B1 biosynthesis and accumulation

A modified fluorometric method for the determination of thiamine in food is described. The procedure is simple, reproducible, does not demand costly outfit and chemicals and is not susceptible to interference. The recovery of added thiamine is good.
Zubair Anwar et al.
Journal of photochemistry and photobiology. B, Biology, 203, 111766-111766 (2020-01-14)
The photolysis of thiochrome (THC), an oxidation product of thiamine (vitamin B1) (THE), used for its fluorimetric assay, has been studied in the pH range 7.0-12.0. THC undergoes photooxidation to oxodihydrothiochrome (ODTHC) which is oxidized to a non-fluorescent compound (OP1)
