General description

Pyridoxine (vitamin B6) is a form of vitamin B6. Other forms include the aldehyde pyridoxal and the amide pyridoxamine. It is an important cofactor for metabolism.
Vitamin B group are water-soluble and exists in six forms which includes the pyridoxal, pyridoxine, pyridoxamine, pyridoxamine 5′-phospate, pyridoxine 5′-phosphate and pyridoxal 5′-phosphate. Vitamin B6 is distributed in nuts, whole grains and animal meat.


Pyridoxine has been used as a component of:
  • artificial diet for sugarcane aphid pest
  • modified Strullu and Romand (MSR) medium for carrot root organ culture
  • Luria broth for E coli cultures

Pyridoxine is used in cell culture and other applications as a precursor to pyridoxal phosphate. It has been used as a standard in RP-HPLC (reversed phase high performance liquid chromatography) method. Pyridoxine has been used as a diet supplement to study lipid profile in rats.

Biochem/physiol Actions

Pyridoxine plays a key role in cell maintenance and amino acid metabolism. Deficiency of vitamin B6 leads to anemia especially in pregnant women and seizures in newborns. It serves as cofactor for heme biosynthesis during δ-amino levulinic acid formation, γ-aminobutyric acid (GABA) transaminase and glutamic acid decarboxylase. Vitamin B6 also helps in reactive oxygen species (ROS) scavenging and helps plants in overcoming the abiotic and biotic stress.
