Melanin

man written by Robert Cohen, he said that our skin color is determined by the amount of melanin pigment in our skin. Dark skin has a lot of melanin while Lighter skin have less. Although, the difference in our skin are very real, anthropologies long ago rejected the idea of races connected to skin color because it was believed that there is no culture in color, no muscular or mental abilities connected to melanin, no character trait, virtue or values associated to skin color, yet at an early age children

Over time, those who stayed in Africa had an increased melanin production and gained a ‘black’ complexion (see fig 1.3) whilst those who left for Europe began to grow diverse combinations of pigmentations (red hair w/blue eyes etc.). From this theory, it is then believed all Caucasian’s are branched from Albinistic

Melanin is an important part of the body that is produced by melanocytes. Melanin gives the hair, skin, and eyes color as well as protects the body from the ultra violet rays that radiate from the sun. The amount of melanin in the body determines the complexion of the skin. Vitiligo occurs when these important melanocytes die in patches around the body. This differs from the aging process, when melanocytes stop producing melanin which results in white or gray hair. Vitiligo is a non-contagious, non-life-threatening

to the kangaroos in the outback, albino animals all over the world are being saved in refuges. The term “albino” comes from the Portuguese term “albo” meaning “white skin”. The definition is an animal or person who lacks the ability to produce melanin, a pigment that colors the skin. The reason for this is most likely from heredity, or the pass down of genes from past generations. If the person or animal only has recessive genes, then the offspring has a chance of being albino. The chances of an

Melanin is the pigment responsible for the color of the skin, hair and eyes. People who have albinism are more susceptible to developing skin cancer because there is a lack of melanin produced in the body. Melanin also plays a huge role in the eyes, so the lack of pigment causes them to be extremely sensitive to light, according to the article “Albinism”

the melanocytes, the cells that produce melanin. Melanin is the pigment that gives our skin, hair, and eyes their color and that allows us to tan” (Schofield & Robinson, 2000, p. 1). Melanocytes are located throughout the body, “in the retina of the eye and in the linings of the mouth, nose, anus, rectum, vagina, and spinal cord,” (Schofield & Robinson, 2000, p. 6). However, majority of them are located in the skin. The purpose of these cells are to make melanin to protect our skin cells from the sun’s

in up to seven different genes and are characterized by a complete lack or reduction of the pigment melanin in the eyes, hair, and skin. An estimated 1 in 20,000 people worldwide are born with this disorder. The conditions of OCA are caused by mutations in genes that are responsible and necessary for producing the melanin pigment in specialized cells (melanocytes). Not having enough of the melanin pigment can result in abnormal eye development, resulting in vision problems, and light skin that is

SCREENING OF ANTAGONISTIC ACTIVITY OF MARINE ACTINOMYCETES AGAINST CLINICAL PATHOGENS Ramarajan K*,Karthick .V * P.K.Senthilkumar, Department of Microbiology,Faculty of Sciences, Annamalai University Tamil Nadu, India. Email: ramsmicr@gmail.com Abstract The present study was conducted to examine the ability of six promising indigenous isolates of marine actinomycetes (NA-1, 2, 3, 4 and TA-1, 2) as probiotics in nature. The actinomycetes isolated from these eco systemsare capable of producing

condition is more noticeable on a dark-skin person than a light-skin person.Although , vitiligo affect all other race but, the condition is not life -threatening or contagious. Normally the color of hair and skin is detemined by melanin. Vitiligo occurs when the cell that produce melanin die or stop functioning.It can be very stressful and make you feel ugly and not highly of yourself. Vitiligo is a disorder which , in the skin destoryed. Sometimes the genes of the immune system can play a role in this diseases

affect the skin on any part of the body examples would be hair, the insides of the mouth and even the eyes (Mayo Clinic Staff, 2015). Normally, the color of hair, skin and eyes is determined by melanin. Vitiligo occurs when the cells that produce melanin die or stop functioning (Mayo Clinic Staff, 2015). Melanin is responsible for giving humans their skin, hair and eye color, this pigment is mainly composed of melanocytes cells in the skin and is sometimes referred to as a chemical as part of the metabolizing
