Biologically we are NOT the same❗️ Stop that no sense about we all the same. Could it be that ours is selenium based and theirs is sulphur based.
What is Melanin?
By Dr Ananya Mandal, MD
Melanin is a complex polymer derived from the amino acid tyrosine. Melanin is responsible for determining skin and hair colour and is present in the skin to varying degrees, depending on how much a population has been exposed to the sun historically.
Numerous steps are involved in the biosynthesis of melanin. The first step is catalysis of the chemical L-3,4-dihydroxyphenylalanine by tyrosinase. A lack of tyrosine can lead to albinism. Tyrosine is only found in a specialized cells called melanocytes, inside which tiny granules of melanin pigment are contained in vesicles called melanosomes.
These melanosomes leave the melanocytes and move into other cells in the epidermis. Mostly brown or black in colour, melanin deposits determine the skin pigment which varies depending on the number and distribution of the melanosomes. Aside from determining skin colour, the light absorbent melanin protects the DNA against UV radiation from the sun and it is considered a potential candidate in melanoma treatment.
Melanin is found in several areas of the human body including:
Skin where it provides skin colorHairPupils or irises of the eyesStria vascularis of the inner earAreas of the brain, the substantia nigra and locus coeruleusThe medulla and zona reticularis of the adrenal gland
Types of melanin
Some of the different types of melanin include eumelanin, pheomelanin and neuromelanin. Eumelanin is found in the hair, skin and dark areas around the nipples. It is particularly abundant among black populations and provides black and brown pigment to the hair, skin and eyes
