Melanin

The amino acid Tyrosine synthesizes dopa and dopamine which are then oxidized to form different melanin to produce the pigmentation. In the tan mutation, N-β-alanyl-dopamine hydrolase converts NBAD into dopamine. In a reverse reaction, when dopamine is converted into NBAD through NBAD synthetase, the ebony gene is expressed. A high concentration of…

Stress and grey hair – fact or fiction A popular belief is that stress may cause grey hair. But is that a fact or a fiction? Is it possible that hair turns gray overnight? Many would say it is possible and one of the examples is Marie Antoinette. Supposedly, right before she was guillotined, her hair turned white.

Whether the UV rays are coming from a tanning bed or the sun they can still cause wrinkles, rashes and dark spots. The most dangerous types of UV rays can change the DNA in cells, which is what experts believe is the main cause of skin cancers.In the US, 35% of adults and 55% of college students have…

Without the skin and nerves could not feel sensations such as heat and cold. Why is touching important? According to Tracy Connor, touching…

What are sudoriferous glands, and where are they located? They are sweat glands and they are located throughout the body. 11. What is sweat composed of and what are two functions of sweat?

This paper will touch on how normal cells become cancerous cells through the damaging of DNA. It will thoroughly explain the layers of the human skin. Then the paper will go in more details about a complex interaction of environmental (exogenous and endogenous), including genetic, risk factors in developing malignant melanoma. It will touch on the familial melanomas occur in a familial setting related to mutation of the CDKN2A gene as that encodes p16.4 The purpose of this project is to…

Could our truth be encoded in our genetics? We can now access information about our genomes through genetic testing through companies that analyze, and find errors in, our genome. Genetic testing can help us better understand the current health status of our bodies. It’s vital that we develop an understanding of our internal environments; especially if we seek prosperity for the future without being affected by potential health issues caused by our genetic mutations. Specific diseases (or other…
