Mc1r In Yeast

Human skin contains about the same number of melanocytes for each individual. Melanocytes are found in the epidermis of the skin. It is possible for every skin color to have a similar number of melanocytes because melanocytes produce a substance called melanin. Melanin breaks down into two substances called eumelanin and pheomelanin. Eumelanin is what controls how dark your skin will be. The more eumelanin the darker your skin. Genetics is what will determine how much and what kind of pigment you will have. One of the genes related to your skin color is melanocortin 1 receptor, also known as MC1R. When your MC1R is healthy it helps melanocytes convert pheomelanin into eumelanin. If your MC1R is not healthy this will cause a buildup of pheomelanin. If someone has red hair or very

fair skin there is a good chance that they have a type of MC1R that does not work properly. Another indication of the color of your skin is the amount of sunlight you are exposed to.

Our skin receives ultraviolet rays from the sun. The measure of ultraviolet light rays your skin actually absorbs can be very detrimental to you. Ultraviolet rights can dismantle your folic acid or cause changes in the DNA. These are some ways people can obtain skin cancer. In response to the sun our skin produces Vitamin D. The more eumelanin you have, or the darker your skin, the harder it is for you to make Vitamin D because melanin tends to act as a filter. This means that darker complexions will need be exposed to more sunlight in order to obtain a great deal of Vitamin D. When people are exposed to ultraviolet for an extensive period of time this can cause skin wrinkles. Wrinkles are a sign of lost elasticity in the dermis. The alteration of elastic fibers is what causes the skin to lose its elastic property. A couple other disorders related to the integumentary system include Rosacea and Tinea. Rosacea can be diagnosed by its red appearance around the nose and cheeks. It also looks similar to a rash. A physician would be able to diagnose Rosacea by the fine network of dilated blood

vessels. Rosacea also can also progressively get worse when people drink hot drinks, alcohol, or eat spicy food. This disorder can accurately be diagnosed because it typically begins between the ages of thirty and fifty. There are no specific test to diagnose Rosacea but there are test to rule out other possible disorders. Another disorder of the integumentary system is Tinea. Tinea, on the other hand, is a fungal infection. It is most known for its name “ringworm” because of its circular growth pattern. Tinea is prominent in moist areas such as your armpit, foot, or groin. Tinea tends to be red and itchy and have raised patches. These patches can sometimes ooze or be red on the outside edges. Tinea can be diagnosed easily by a physician by just observing the affected area. If unsure a doctor could take a skin biopsy which would send a sample of your skin or discharge to a lab for testing.
