l-Dopaquinone also known as o-dopaquinone is a metabolite of L-DOPA (L-dihydroxyphenylalanine) and a precursor of melanin. Biosynthesis of melanin occurs...

(melanogenesis) starts with the oxidation of l-tyrosine to l-dopa by the enzyme tyrosine hydroxylase, then to l-dopaquinone and dopachrome, which forms melanin...

melanocytes. Inside the melanocytes, tyrosine is converted into L-DOPA and then L-dopaquinone, which in turn is formed into pheomelanin or eumelanin. Different...

found in the KEGG database (see External links). L-tyrosine L-DOPA L-dopaquinone L-leucodopachrome L-dopachrome Melanin is brown, non-refractile, and...

formula C9H9NO4 (molar mass: 195.17 g/mol) may refer to: L-Dopaquinone, also known as o-dopaquinone Pencolide Salicyluric acid This set index page lists chemical...

catalysis of tyrosine by an enzyme called tyrosinase, producing dopaquinone. Dopaquinone may become eumelanin, or phaeomelanin. Eumelanin, meaning true...

intermediate dopaquinone, which reacts further, eventually leading to melanin oligomers. In addition, tyrosinase can convert tyrosine directly to l-DOPA in...

melanin production: the hydroxylation of tyrosine to l-DOPA and the oxidation of l-DOPA to dopaquinone. By inhibiting tyrosinase, α-arbutin reduces the formation...

hydroxylation of tyrosine, an amino acid, to l-DOPA (levodopa) and the oxidation of d-DOPA to dopaquinone which is then further metabolised to melanin...

oxidative transformation of catechol derivative dopa to light absorbing dopaquinone to indole-5,6-quinone is clearly seen following the polymerization to...
