Ascorbic acid and melanogenesis
British Journal of Dermatology, 1977The ascorbic acid contents of skin, plasma and urine were estimated in 12 vitiligo cases, one albino and 10 normal subjects. All the estimations were repeated after saturation with ascorbic acid. There was no difference between the two groups with regard to the ascorbic acid contents of their plasma or urine.

Es wurden die anatomische und subzellulare Verteilung der Tyrosinaseaktivitat im Integument und die Tyrosincarboxylinkorporation in Melanin beiRana pipiens undRana catesbiana festgestellt und gefunden, dass die Tyrosinaseaktivitat in der Bauchhaut hoher ist als in der Ruckenhaut, wahrend die Seitenhaut dazwischenliegende Werte liefert.

Quinone Chemistry and Melanogenesis
2004Publisher Summary The divergence of the melanogenic pathway occurs after the initial oxidation step that yields dopaquinone. The current analytical approach to the classification of melanins depends on the assessment of the comparative levels of degradation products that are considered characteristic of indoles and benzothiazine residues.

The structure of melanins and melanogenesis—III
Tetrahedron, 1962Abstract A comparative study on sepiomelanin and three synthetic pigments, namely dopa melanin, 5,6-dihydroxyindole melanin and pyrrole black, has been carried out. Sepiomelanin is structurally related to 5,6-dihydroxyindole and dopa melanins. The only observed differences are the absence of carboxyl groups in position 2 of the indole nuclei in the ...

The Chemistry of Melanins and Melanogenesis
1995Some twenty years have passed since Swan reviewed the chemistry of melanins for Vol. 31 of this series (1). Although some of the questions which he aired at that time have remained unanswered, our knowledge and appreciation of the field have increased dramatically in the intervening years (2, 3). Considerable steps forward have been made in practically
