Melanogenezis
Melanogenezis is the biological process by which melanin, a pigment responsible for skin, hair, and eye color, is produced. It occurs in specialized cells called melanocytes, which are found in the basal layer of the epidermis in the skin and in the iris and ciliary body of the eye. Melanin is synthesized from the amino acid tyrosine, which is converted into dopa through the action of the enzyme tyrosine hydroxylase. Dopa is then converted into dopaquinone, which is further processed into eumelanin or pheomelanin, the two main types of melanin.
Melanin serves several important functions in the body. In the skin, it protects against ultraviolet (UV) radiation
Melanogenezis is regulated by various factors, including hormones, genetic mutations, and environmental influences. For example, exposure
Abnormalities in melanogenezis can lead to a range of conditions, including albinism, vitiligo, and melanoma. Understanding
