l-Dopaquinone also known as o-dopaquinone is a metabolite of L-DOPA (L-dihydroxyphenylalanine) and a precursor of melanin. [1] [2]
Biosynthesis of melanin occurs in melanocytes, where tyrosine is converted into DOPA and then dopaquinone, which goes on to be formed into pheomelanin or eumelanin. [3]
