Melanin is secreted by melanocytes that are distributed in the basal layer of the skin epidermis[1]. Melanin is responsible for skin color and also plays a key role in protecting the skin against ultraviolet (UV) sunlight damage. Various dermatological disorders result from the accumulation of an...

Melanin is another skin pigment molecule responsible for skin aging. The present study aims to investigate the relationship between melanin production and lipofuscin synthesis in normal mouse melanoma cell line B16F1 cells and Tyrosinase (TYR) gene knockout cells. TYR gene KO cells were successfully ...
Melanin is a dark biological pigment (biochrome) occurring in the skin, hair, feathers, scales, eyes, and some internal membranes of humans and other animals. It is formed as an end product during metabolism of the amino acid tyrosine.

Melanin is the name of the biological pigment that determines the general color of skin and hair in humans. Forms of melanin are responsible for coloration throughout the animal world; for example, wing coloration in birds is produced by melanin. In addition, the cells that produce melanin, ca...
is required before it can be used to develop new materials. Recent research shows that melanin is actually a general term for a group of heterogeneous pigments produced by organisms in all areas of life, from bacteria to mammals. In humans, melanin is the leading pigment responsible for skin,...
