- Function of skin pigment. Melanin is a naturally produced polymer found in a multitude of locations in the body, from the eye and ear, to the brain and skin.Each different location contains a different variety of melanin, such as neuromelanin in the brain, and eumelanin and pheomelanin in the skin.kin colour is determined by: 1  The ratio of eumelanin to pheomelanin, where the more eumelanin present, the darker tone of an individual; 2  The absolute amount and concentration of melanin in the skin; and.

What is the function of Melanin Pigment? Eumelanin is brown or black color pigment and protects the skin from absorbing the harmful UV rays. People with darker skin tones have more of Eumelanin.This is the reason melanin pigments are called as photo-protectants which means a substance that can provide protection from the harmful sun rays.

Hormones in Ethnic Skin Human skin color can vary from almost translucent to almost black. This range of colors comes from the amount and type of a pigment called melanin found in the skin. There are two types of melanin--eumelanin and pheomelanin. In general, the more eumelanin in your skin, the darker your skin will be. People who make more pheomelanin than eumelanin tend to have lighter skin with freckles. Like many other traits, the amount and kind of pigment in your skin is controlled by genes.

Eye Color The colored part of the eye is called the iris, which has pigmentation that determines our eye color. Her eyes may be blue only temporarily; babies' eyes can change color if the brown pigment melanin develops as they grow. Human eye color originates with three genes, two of which are well understood.

- An individual with complete absence of melanin is called an albino. One with only a small amount of melanin is described as albinoid. People with albinism are very pale with fair hair and very light eyes. In some people, the eyes appear red or purple, depending on the amount of pigment.This can happen because the iris actually has very little color. The eyes appear pink or red because the blood vessels inside of the eye show through the iris.t is characterized by a deficit in the production in melanin and by the partial or complete absence of pigment in the skin, hair and eyes. This hereditary disease can be found in humans (affecting all races), mammals, birds, fish, reptiles and amphibians.

What is Melanin? Also called pigment, melanin is a substance that gives the skin and hair its natural color. It also gives color to the iris of the eye, feathers, and scales. In humans, those with darker skin have higher amounts of melanin.By contrast, those with less pigment have lighter or more fair skin coloring.Melanin, sometimes referred to as a chemical, is formed as part of the process of metabolizing an amino acid called tyrosine.In the skin, melanin is formed by cells called melanocytes.y contrast, those with less pigment have lighter or more fair skin coloring.

The Iris Some pigment causes the iris to appear blue. Increasing amounts of iris pigment produce green, hazel, and brown irises (or irides). There actually are two pigments, melanin and lipochrome, which determine eye color. Melanin (brown) deposition is controlled by a gene on chromosome 15.

Albinism Albinism is a defect of melanin production. Melanin is a natural substance in the body that gives color to your hair, skin, and iris of the eye. Albinism occurs when one of several genetic defects makes the body unable to produce or distribute melanin.

- Specilized cells in the epidermis called melanocytes produce melanin, a dark pigment that provides skin color. Melanin absorbs ultraviolet radiation in sunlight and preventing mutations in the DNA of skin cells and other damaging effects.ifferences in skin color result from differences in the amount of melanin that melanocytes produce and the distribution and size of pigment granules. Skin color is genetically determined.

Human skin color People have different skin colors mainly because their melanocytes produce different amount and kinds of melanin. The genetic mechanism behind human skin color is mainly regulated by the enzyme tyrosinase, which creates the color of the skin, eyes, and hair shades. Differences in skin color are also attributed to differences in size and distribution of melanosomes in the skin. Melanocytes produce two types of melanin.

Human hair color Two types of pigment give hair its color: eumelanin and pheomelanin. Pheomelanin colors hair orange and red. All humans have some pheomelanin in their hair. Eumelanin, which has two subtypes of black or brown, determines the darkness of the hair color. A low concentration of brown eumelanin results in blond hair, whereas a higher concentration of brown eumelanin results in brown hair.
