State the location and function of melanin?
Answers
The melanin Function:
The skin is considered as a pigment gland, form because melanin, which is a dark pigment that gives us the color. Skin there are two types of melanin: Dark eumelanin and Feomelanina, lighter color.
The normal skin color is related to the number, size, type and distribution of these melanosomes in keratinocytes, melanin disintegrates and disperses in the keratinization process to the upper layers of the epidermis.
These are specialized organelles that contain melanin; the melanocytes produced, after being transferred to the keratinocytes. The amount of melanosomes in the keratinocytes is present which determines the color of the skin and hair.
In this role involved melanocytes, cells found in the basal layer of the epidermis between keratinocytes, who form melanin, pigment that gives color to the skin.
Or the production of melanin synthesis is due to an enzymatic reaction. The enzyme which oxidizes and darkens the melanocyte is called tyrosinase. Imbalances in the melanin operating anomalies occur as dyschromias.
Black colored individuals have the same amount of white melanocytes, but these are larger and more active.
Accelerators are light melanogenesis, heat and repeated minor trauma and a solarium. Sun exposure causes melanin synthesis, therefore the skin tans. The melanin function is essential defense against the carcinogenic action of ultraviolet rays from sunlight. Factors governing its operation: hormonal and sunlight.
The keratin Function Melanocytes are melanin-producing neural-crest derived cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea), the inner ear, meninges, bones, and heart.Answer:
Melanin location is epidermis. It is the pigment of colouration of skin.
