1, what makes melanin? Melanin is extensive consist in the person's skin, mucous membrane, retinal, piamater and gallbladder and ovarian wait place. Melanin is by melanin cell complex. Cutaneous melanin cell basically distributings the base layer in skin, also see scabbard of the wool outside be being reached at Mao Gen. The person's skin has cell of 2 billion melanin about, make an appointment with one gram again, average every square millimeter distributings 1560 times symmetrically at the whole body. 2, how does melanin arise? Melanin cell can be synthesized and secrete melanin, because this is cell of a kind of gland. However the biosynthesis of melanin is very complex, it is to adopt black system (crudely melanin) inside cheese ammonia is acerbity - sour enzymatic reaction forms cheese ammonia. 3, what does the factor that affects Hei Suge to become metabolization have? Of melanin generate, in move and degradation process, any link produces an obstacle to all can affect its to metabolize, cause change of place skin color. Basically have the following kinds of cases via research: (1) cheese ammonia is acerbity, cheese ammonia enzymatic reaction is done approach. With ascorbic acid (vitamin C) for exemple, if ascorbic acid is added in this one reaction, can prevent much cling to melt into of Kun farther oxygen is much cling to pigment, make already complex is much cling to Kun by reductive for how cling to, melanin of as a result cannot be synthesized. (2) black body enters suffocate suffocate of process of divide with a hyphen at the end of a line of horny protein cell to adjacent from melanin cell. Observe discovery for years via us: Color of human body skin basically differs because of the active difference of melanin cell, but skin color does not follow the black inside melanin cell to system adds and be deepened certainly, and basically depend on black body from melanin cell in the process to divide with a hyphen at the end of a line of cell of adjacent horn protein whether unobstructed. After if the pigment after dermatitis disease is taken off,be damaged as a result of cuticular cell, black body cannot be excreted through free through cuticular cell, and bring about sluggish of black body block within melanin cell, make afterwards sends melanin cell function to drop. (3) of black body generate, degradation is slow. Clinical the cyan pigment that goes up to arrive it is thus clear that is unusual spot of the mole that be like blueness, Mongolia, too cropland mole, Yi Tengshi mole, all as a result of body of the black inside dermal melanin cell generate, degradation has slow friend. (4) ultraviolet ray. Usually, ultraviolet ray can make acerbity enzymatic active enhances ammonia of the cheese inside melanin cell, grow in quantity of nigrify pigment cell, black body is generated exuberant, shift is accelerated. (5) Qiu radical. There is a kind of organic compound inside human body skin - Qiu radical compound, especially among them Gu Guanggan peptide, can pass complexing copper ion and restrain enzymatic active of cheese ammonia acid, somebody determines skin Qiu base content, skin of damage of patient of wind of discovery white purplish or white patches on the skin is medium Qiu radical content (157 milligram element is measured / 100 grams weight in wet base) than normal person (1.55 × 10- 2
