Melanin is an irregular light-absorbing polymer containing indoles and other intermediate products derived from the oxidation of tyrosine. Melanin is widely dispersed in the animal and plant kingdoms. It is the major pigment present in the surface structures of vertebrates.

A review focuses on the pigments derived biogenetically from tyrosine and produced intracellularly within specialized cells. Melanin pigments, eumelanins and pheomelanins, can be described today as collections of mol. species with different chem. structures and properties, thus encompassing diverse degrees of chem. heterogeneity.

Chemical Degradation of Melanins: Application to Identification of Dopamine‐melanin
Pigment Cell Research, 1998Melanocytes produce two chemically distinct types of melanin pigments, eumelanins and pheomelanins. These pigments can be quantitatively analyzed by acidic KMnO4 oxidation or reductive hydrolysis with hydriodic acid (HI) to form pyrrole‐2,3,5‐tricarboxylic acid (PTCA) or aminohydroxyphenylalanine (AHP), respectively.

Binding of memantine to melanin: influence of type of melanin and characteristics.
Pharmaceutical research, 2003The objectives of this study were to characterize sepia, synthetic, and bovine melanin and to determine their binding characteristics to the drug memantine.Physical methods were used to characterize sepia, synthetic, and bovine melanin. Their binding properties toward memantine were determined in deionized water and phosphate-buffered saline (PBS) at ...

Therapy of Melanin Hyperpigmentation
Postgraduate Medicine, 1965Hydrocortisone is effective in therapy of hyperpigmentation associated with adrenal hypofunction. It is also of value in pigmentary disorders attending pruritic dermatitis. Adrenal function is normal in the latter cases. Excessive melanocytestimulating hormone may be responsible for the hyperpigmentation.Chloasma must be evaluated carefully before ...
