püridoksal5fosfaati
Pyridoxal 5-phosphate, often abbreviated as PLP, is the biologically active form of vitamin B6. It is a coenzyme found in all living cells and plays a crucial role in a vast array of biochemical reactions. PLP is essential for the metabolism of amino acids, serving as a cofactor in over 100 enzymatic reactions, including transamination, decarboxylation, and deamination. These processes are vital for protein synthesis, neurotransmitter production, and the breakdown of glycogen.
The structure of PLP consists of a pyridine ring with a phosphate group attached at the 5-position.
Deficiency in vitamin B6, and consequently PLP, can lead to a range of health issues. These may
