CHE SIGNIFICA MELANIN IN INGLESE
melanina
Melanin i / mɛlənɪn / è un termine ampio per un gruppo di pigmenti naturali trovati nella maggior parte degli organismi. Il melanina viene prodotto dall'ossidazione della tirosina dell'aminoacido, seguita dalla polimerizzazione. Il pigmento viene prodotto in un gruppo specializzato di cellule noti come melanociti. Esistono tre tipi fondamentali di melanina: eumelanina, pheomelanina e neuromelanina. Il tipo più comune è eumelanina, e viene prodotto in sottotipi "neri" e "marroni". Pheomelanin è un polimero rosso-marrone contenente cisteina di unità benzotiazine in gran parte responsabile di capelli rossi e freckles. Neuromelanin si trova nel cervello, anche se la sua funzione rimane oscura. La produzione di melanina è chiamata melanogenesi. Nella pelle, la melanogenesi si verifica dopo l'esposizione a radiazioni UV, causando la pelle visibilmente abbronzante. Melanina è un efficace assorbitore di luce; Il pigmento è in grado di dissipare oltre il 99,9% di radiazione UV assorbita. A causa di questa proprietà, il melanina è pensato per proteggere le cellule della pelle dai danni da radiazioni UVB, riducendo il rischio di cancro.
