Black-melanin pigments, which are in high polymeric compounds formed in enzymatic oxidation of phenols, mainly pirokatehina and tirozina, and their subsequent polymerization. The structure is unreliable and melaninov varies greatly. Melanin found in animals, plants and fungi, giving them a dark color. They determine, for example, a dark pigmentation of skin, hair, skin many fruits, black coloring of many colonies of mushrooms, including the so-called "black yeast." Melanin perform protective function. It has been shown that the types of fungi that form melanin, on average, more resistant to various types of radiation, including radiation and ultraviolet, dry and high temperature and Explain the protective function of Melanin.
For buildings and chemical properties of melanin mushrooms quite similar to guminovymi acids. Therefore, it is possible that mushroom melanin plays an important role in the education of soil humus... Explain the protective function of Melanin.

Melanin is a special pigment that gives the skin and hair its natural color. It makes the skin tanned, but also produces unwanted freckles, birthmarks and other colored marks on the body.Explain the protective function of Melanin - More Details
With humans melanin forms in special sea-star shaped cells called melanocytes in the basal layer of epidermis and then transforms into granules where pigments are combined with protein. Melanocytes inject melanin grains into the cells of the upper skin layer (cortical layer of the hair and the iris of the eye) and determine their color.Explain the protective function of Melanin - Doctors view
Doctors from time to time state that tea, coffee, chocolate and cacao are harmful for our health. However, it is no good to give up these products once and for all as they contain melanin that is essential for the human organism. Also prunes, bilberry or dark grapes are good protection against cancer, sunburns and influence of radiation.The review discusses the biochemical principles of pharmacological action of a natural cell-melanin pigments. Recently obtained data on the effect of different pharmaceutical melanin in the treatment of diseases of different genesis, indicating his Explain the protective function of Melanin.
Showing that melanin involved in the reparations DNA processes functioning respiratory chain as electron acceptor, is a major modulator of such systems, cellular metabolism and photographs Explain the protective function of Melanin, neutralizes peroxide oxidation products lipidnov Melanin and participates in many pathological processes in violations of the functional structures of neurons. Experimental data obtained in the study of metabolism of melanin, are not always able to clearly explain the mechanisms of action of pigment, and therefore, there is need to systematize data on the literature melanin pigments for the purpose of possible use of pigments to create various dosage forms and Explain the protective function of Melanin.
Explain the protective function of Melanin Introduction. Recently, in research related to the issues of theoretical medicine, becomes the highest priority direction for the study of natural effectors for the treatment of diseases with different genesis. This is due primarily to the fact that natural metabolites (or their equivalent), not only have high specificity to the individual cell systems exchange, but can easily adapt to the system of transport across cell membranes. In addition, when using natural components not violated the regulation of cellular metabolism: specific impact on a specific system is a shift from other metabolism-type chain reaction. Therefore, the benefits of regulatory actions apparently of natural compounds. In connection with the above, against the background of widespread use of naturally occurring compounds special attention to professionals working in the field of drug-melanin drawn to the natural pigments cell belonging to a group nizkomolekulyarnyh phenolic compounds... Explain the protective function of Melanin.

Explain the protective function of Melanin - Good Hair
Having a good hair day doesn’t just happen by chance. It happens when taking care of your hair becomes just as important as taking care of your skin. But what do you do when your hair has been damaged by every day styling, and chemical processing, dyeing or perming? Is there any solution for fly-away hair, dullness and faded color?Explain the protective function of Melanin - Science view
The color of hair is determined by the amount of melanin in the cortical layer. Dark hair has a lot of pigment while fair hair has fewer granules that are of smaller size. Diffusive or non-granulated melanin makes the hair red. Hair, like any other part of the body, requires essentials nutrients for growth and survival.

As you know, the coloring of skin color diversity of animal and plant organisms provided by the availability of cell melanin, distinguished by the chemical nature and structure depending on the species belonging organism. Until recently, biochemical studies melanin role in the cell were conducted fairly passive. Understand that the system functions in addition to pigment melanin synthesis involves electron transport system in the respiratory chain, as is well known that one of the metabolites exchange melanin is ubihinon, who serves in the redox intermediate element of the transfer of electrons from Explain the protective function of Melanin.Experimental work on the nature and characteristics of their melanin revealed Explain the protective function of Melanin metabolism of these compounds [2, 3]. Although the chemical structure of natural melanin are still not identified because of their extremely complex polymer structure and the large variety, pharmacological effects melanin fairly intensively studied. Specific properties of the pigments that make them like molecular sieves, and ion-exchange resins, high elektro-aktsept capacity, the availability of stable free radicals in high concentrations and pronounced semiconductor properties of melanin allows successfully used in medicine, pharmacology and other industries. We detected that as a result of sustained Explain the protective function of Melanin and ability to oxidize and recover melanin protects the body from the extreme conditions that may generate in a living cell active Explain the protective function of Melanin radicals violating processes of an.
In doing so, it should be noted that currently there is not even a consensus about what, in fact, the content should invest in the concept of melanin. " For example, Mason and the staff regard them as high polymers, which are formed when Melanin oxidation of phenols, mainly Melanin - Melanin (DOFA). Close interpretation gives Nikolaus. However, all these authors are reminded that there is a fairly large group of pigments, variruyuschih color from yellow to svetlo-korichnevyh but biologically and chemically nerodstvennyh black or brown pigments, which are also known as melanin. " Thomas and collaborators proposes to call melaninami only black pigments nitrogen - indole derivatives. Dark pigments - phenols fiber oxidation products (eg pirokatehina) excludes them from that notion.

However, metabolic and strukturno-funktsionalnye especially melaninov allowed to put them on one stage with such life-saving effectors cell homeostasis as proteins and DNA. In one of the best to date review of microbial melaninam SP Lyakh, observed that ". Melanin served as a rewarding material for the chemical evolution of some predbiologicheskih structures. Possibility of this stems from the nature of the process of synthesis and properties of these substances" modern "melaninov. Addition, much attention is the ease with which these pigments synthesized in simulation environment, presumably existed in the timing of the Earth more complex aromatic substances from pervostruktur. Blois, one of the largest biofizikov working with melaninami, believes that the issue than was the first polymer-protein or DNA, someday may have to answer-melanin Explain the protective function of Melanin.Thus, despite the fact that periodically appear in the literature work on the local action melanin to any system or process of cellular metabolism, fully difficult to physiological role of regulatory action and place in life melanin cells, since the study dealt with the nature of melanin , in the main, microbiology. The purpose of this review is to try to systematize information on the physicochemical nature melanin, biochemical characteristics and their pharmacological effects. Dampening lick lips through mucous membranes, however, do not fully protect the "naked" keratin (like the skin) or even emidinom (as a red border) epithelium. Developed signs of inflammation: dryness, blood, swelling, increased desquamation. Protective, and then Pathological deskvamativnaya response exacerbates vulnerability cover and contributes to the further development of pathology.
A so-called "meteorological" heylit that can and evolved, in turn eksfoliativny.
If the same in the corners of the mouth are not Hermeticism in closing, the corners of the mouth, deep in the folds will be constant humidity, unusual for the skin and red border. In this case develops custom epithelium and protective function of Melanin.
Because of the unity created for skin and red edging the external environment drawing smaller teeth and skin red edging loses independence, becoming a single, red edging borders as a blurred, cracks appear in the corners of the mouth, develops chronic angulyarny heylit (zaedy "). As the importance of microflora in the formation of these species heylita high, and it should be treated antimicrpobial vigorously. The availability of child Zaed propensity age (and the elderly) when protective properties and morphology cover fabrics are imperfect (involyutivno immature or reduced). Treatment with the use of vitamin A in fat solution has not so much eliminating gipovitaminoz effect, but rather help to protect the epithelium by fat packs, provide better conditions for cover fabrics. The main element in the development angulyarnogo, like other heylitov, is a violation of protective forces saliva and Explain the protective function of Melanin.
