The color of our skin is determined by the amount and type of melanin produced, as well as its distribution in the surrounding skin cells (keratinocytes). There are two main types of melanin produced in the skin: Eumelaninis a brown-black pigment, and the most common pigment that we see ...
In order to contribute to the ongoing efforts to identify the genes that generate this polymorphism we have tested the long-standing assumption that melanin is the pigment that comprises the dark-brown bands. Surprisingly, using a newly established analytical chemical method, we find no evidence ...
Melanin is a pigment, typically present in mammalian hair, skin, and eyes, and equally widespread in birds, lizards and insects33. Its most common function is to absorb light, to protect animals from ultraviolet radiation or to generate cryptic colouration. In insects, melanin is generally ...
Albinism is caused by a genetic mutation that affects the production of melanin. Melanin is the pigment responsible for coloring the skin, hair, and eyes. It is typically inherited when both parents carry the gene mutation. There are two main types of albinism:1) Oculocutaneous Albinism (OCA)...
The pigment melanin, which is produced by many fungi and Streptomycetes can bind trace elements to its carboxylic groups and was shown to be involved in trace element sorption and trace element tolerance of S. scabies (Haferburg and Kothe, 2010). Molecular structures and functional groups of ...
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...
Firstly, sequencing the genes responsible for biosynthesis of melanin (ALB1, AYG1, ARP1, ARP2, ABR1 and ABR2) showed point mutations (missense mutation, deletion or insertion) in the ALB1 gene for pigmentless isolates or in ARP2 for the brownish isolate. The isolates were then shown by...
