Pyridoxal 5 Phosphate, P5P is the active form of vitamin B6. Adequate B6 helps maintain stable energy levels. As a cofactor for a variety of enzymes, it can participate in amino acid transamination, deamination, carboxylation, decarboxylation and other reactions. It is used in dietary supplements, biomedicine and functional foods.

What is pyridoxal 5 phosphate used for?

1. It is one of the important biological catalysts.
P5P is the coenzyme form of vitamin B6. It is involved in more than 100 enzymatic reactions.
2. PLP is involved in a variety of metabolic processes in the body and participates in amino acid metabolism. Other roles include protein metabolism.
3. In addition, it also converts 5-HTP into serotonin, which helps maintain a healthy nervous system. PLP is also involved in the synthesis of neurotransmitters such as adrenaline and dopamine.
