Descrição geral

Pyridoxal 5′-phosphate (PLP), an active form of vitamin B6/ pyridoxine is the coenzyme of amino acid metabolism.

Aplicação

Pyridoxal 5′-phosphate monohydrate has been used:
  • as a component in the reaction mixture for ornithine decarboxylase (ODC) activity assay
  • as a standard to quantify the concentration of pyridoxal 5′-phosphate (PLP) in cerebrospinal fluid (CSF) of children
  • as a dietary supplement to study its effects on the lethal phenotype of mutant flies

Ações bioquímicas/fisiológicas

Pyridoxine participates in the production of lipid and neurotransmitters. Pyridoxal 5′-phosphate (PLP) serves as a cofactor to stabilize carbanions at Cα of amino acids. Pyridoxine deficiency results in peripheral neuropathy. Absence of PLP leads to neonatal epileptic encephalopathy. PLP acts as a coenzyme in transamination, decarboxylation and deamination reactions such as the conversion of dopa into dopamine; of glutamate into γ aminobutyric acid (GABA); of histidine to histamine. PLP works mechanistically through formation of a Schiff-base.
