New Publication on the Analytics of Vitamin B6
As a co-enzyme for over 150 biochemical reactions, Vitamin B6 influences a substantial portion of the human metabolic enzymatic activity. The metabolically active form of vitamin B6 is the vitamer pyridoxal-5’-phosphate (PLP). Pyridoxal (PL) together with pyridoxine (PN) and pyridoxamine (PM) as well as the respective phosphates (PLP, PNP, PMP) make up the group of B6-vitamers. Additionally, plants can contain up to 70 % of the total vitamin B6 content as pyridoxin-glycoside (PNG).
In a recent publication, the authors Bachmann, Maurer and Rychlik report the development of a stable isotope dilution analysis (SIDA) LC-MS/MS method for the quantification of five B6 vitamers in different vegetables, fruits and wheat flower.
