Now, you might be asking yourself what does melanin have to do with ultra-violet light? Well, the DNA molecules are all covered with melanin. One of the things that melanin does is it actually absorbs ultraviolet radiation. Melanin is constantly reaching out towards the ultraviolet rays of the sun. Ultraviolet radiation has been found to be dangerous to protein. When protein is passed through ultraviolet radiation it actually causes the molecule to blend. . When ultraviolet rays are exposed to the chromosomes or the genes, in order for your genes to be able to do what they are suppose to do naturally, they have to be able to change. But when they are exposed to ultraviolet radiation they can’t. Thus when the time or need comes for it to change they will not be able to change. This will result in deformities in your body
Melanins have very diverse roles and functions in various organisms. A form of melanin makes up the ink used by manycephalopods as a defense mechanism against predators. Melanins also protect microorganisms, such as bacteria and fungi, against stresses that involve cell damage such as UV radiation from the sun and reactive oxygen species. Melanin also protects against damage from high temperatures, chemical stresses (such as heavy metals and oxidizing agents), and biochemical threats (such as host defenses against invading microbes) Therefore, in many pathogenic microbes (for example, in Cryptococcus neoformans, a fungus) melanins appear to play important roles in
virulence and pathogenicity by protecting the microbe against immune responses of its host. In invertebrates, a major aspect of the innate immune defense system against invading pathogens involves melanin. Within minutes after infection, the microbe is encapsulated within melanin (melanization), and the generation of free radical byproducts during the formation of this capsule is thought to aid in killing them. Some types of fungi, called radiotrophic fungi, appear to be able to use melanin as a photosynthetic pigment that enables them to capture gamma rays and harness its energy for growth.
The black feathers of birds owe their color to melanin; they are much more readily degraded by bacteria than white feathers, or those containing other pigments such as carotenes. In bird eye, a specialized blood vessels rich organ,pecten oculi is also extremely rich in melanin, which has been considered to have role in absorption of light falling on optic disc and using it to warm up the eye. This, in turn may stimulate release of nutrients from pecten oculi to retina, via vitreous; it is plausible as bird retina is devoid of its own blood vessels. In pigment epithelium of retina, presence of high amounts of melanin granules, may also minimize back-scatter of image light on retina.
In some mice, melanin is used slightly differently. For instance, in Agouti mice, the hair appears brown because of alternation between black eumelanin production and a yellow variety of pheomelanin. The hairs are actually banded black and yellow, and the net effect is the brown color of most mice. Some genetic irregularities can produce either fully black or fully yellow mice.
