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.

Kojic acid (Standard)
0 ImagesKojic acid (Standard) is the analytical standard of Kojic acid. This product is intended for research and analytical applications. Kojic acid is a substance produced by Aspergillus oryzae, with various biological activities including antitumor, insecticidal, antibacterial, antioxidant, and radioprotective effects. Kojic acid exhibits tyrosinase inhibition activity by capturing copper ions that bind to the active site of tyrosinase, preventing its activation. Tyrosinase is a key enzyme in the biosynthesis of melanin, so kojic acid can block melanin production. Additionally, kojic acid shows potential inhibition of NF-κB activity in human keratinocytes, which may also be related to the anti-melanogenic effect induced by kojic acid. Kojic acid is effective when administered orally and can also be absorbed transdermally. Nano-carrier systems prepared with kojic acid demonstrate effective delivery of anticancer drugs. Kojic acid holds promise for research in cancer, infectious diseases, and skin whitening among other fields.
