Pyridoxal-5-phosphate (plp or p-5-p) is the main metabolically active coenzyme form of Vitamin B-6. It is primarily in the liver that p-5-p is synthesized from pyridoxine, with the help of enzymes that require b-2, zinc and magnesium for their activity. P-5-p is associated with numerous enzymes, many of which are involved in amino acid metabolism, necessary to produce the neurotransmitters dopamine, noradrenalin, gaba, and serotonin, as well was the hemoglobin in red blood cells.
