Causes depigmentation of vitiligo melanin

Many patients have been unclear how they are suffering from vitiligo, has been kept in the dark, our hospital experts to answer your questions at: Vitiligo is because of their melanin reduction, depigmentation of melanin in the skin tyrosinase activity decreased or absolute lose, to interpret why vitiligo melanin depigmentation. Melanin depigmentation of vitiligo cases simply because the body into tyrosine is not sufficient, to be added to food through tyrosine remedy.
Tyrosine is not just black melanin predecessor and also thyroid hormones and catecholamine predecessor. Hyperthyroidism revealed that melanin production messy, can be interpreted as a result of increased dairy consumption in the process of nitric acid formation of thyroid hormones, so the skin concentrations of tyrosine liquid loss, depigmentation of skin melanin content decreased tyrosine It reported.
Tyrosine oxygen into two by phenylalanine (DoPa) melanin is the first one links. Oxygen is in the process of Moet neuraminidase - under copper phenol enzyme utility purposes of this enzyme in turn DoPa of oxygen. Some people think that, because UV mapping SH group of oxygen and motivate melanin calm. But many people find SH group content of the lesion in the skin are not increased, also normal.
To animals without food can melanin depigmentation copper, trace elements such research vitiligo which is a push. Vitiligo blood checked clear and depigmentation of melanin in the skin of patients with decreased copper content, copper content increased melanin calm this time around four bands. Clearly, copper ion melanin depigmentation lesions within inadequate can affect the activity of tyrosinase. However, application of copper preparations treatment does not solve the problem. Utility sulfhydryl (SH) includes a blocking function of tyrosinase in the copper ions, thus restricting the activity of the enzyme.

Thus, motivate melanin depigmentation of vitiligo, generated from a chain of vitiligo melanin all known aspects of the activity or the copper content of tyrosinase only more or less deliberated. Up to now there is no exact content of such a material made of vitiligo patients phenylalanine and tyrosine melanin predecessor, the patient can be more understanding of vitiligo knowledge.
