Tyrosinase
Tyrosinase is a copper-containing metalloprotein belonging to the type-3 copper protein family, together with haemocyanins and catechol oxidases. Tyrosinases are the catalysts in mammals responsible for the formation of melanin in skin and hair color, as well as browning in fruit and vegetables following cell damage.
Tyrosinases are found in various prokaryotes as well as in plants, fungi, arthropods, and mammals and are responsible for pigmentation, wound healing, radiation protection, and primary immune response. Tyrosinases perform two sequential enzymatic reactions: hydroxylation of monophenols and oxidation of diphenols to form quinones which polymerize spontaneously to melanin. In plants, sponges, and many invertebrates, tyrosinases are important for wound healing and primary immune responses; in arthropods, they play a role in sclerotization, and in bacteria, tyrosinases protect DNA from UV damage.

N-Acetylneuraminic acid
0 ImagesN-Acetylneuraminic acid (NANA; Lactaminic acid), a nonphenolic structure, is the predominant form of sialic from Collocalia esculenta. N-Acetylneuraminic acid plays a biological role in myocardial injury, melanoma and viral or bacterial infection. N-Acetylneuraminic acid inhibits melanogenesis by reducing tyrosinase activity and triggers myocardial injury in vitro and in vivo by activation of the Rho/Rho-associated signaling pathway through binding to RhoA and Cdc42. N-Acetylneuraminic acid may prevent high fat diet (HFD)-induced inflammation and oxidative stress, thereby prevents hyperlipidemia-associated inflammation and oxidative stress. N-Acetylneuraminic acid is promising for research in the field of melanoma, coronary artery, obesity-related diseases and hyperlipidemia.
