We quantified pyridoxal 5'-phosphate (PLP), pyridoxal (PL), and 4-pyridoxic acid (PA) in paired serum and cerebrospinal fluid (CSF) samples from children and investigated the effect of age on the concentrations and CSF-to-serum ratios of these vitamers.Serum and CSF samples prospectively collected from 49 pediatric patients were analyzed.

Pyridoxal Derivatives in Transamination
Nature, 1952IN living systems a transfer of amino groups occurs between certain amino-acids and keto-acids. This important reversible process, known as ‘transamination’1, effects a link between carbohydrate and protein metabolism, and the responsible enzymes, the transaminases, are activated by pyridoxal2 or pyridoxamine phosphates3. The proposed mechanisms of the

Reaction of dithionite and bisulfite with pyridoxal and pyridoxal enzymes
Analytical Biochemistry, 1969Abstract Both bisulfite and dithionite produce marked changes in the spectra of pyridoxal, pyridoxal phosphate, and pyridoxal phosphate enzymes. The spectrum of pyridoxal phosphate in bisulfite solutions resembles that of the addition product of pyridoxal phosphate with cysteine.
