ʻO nā mea hoʻonani keʻokeʻo a me ka Metabolism Pigment

ʻO nā mea hoʻonani keʻokeʻo a mePigmentʻO ka metabolism

Hoʻokaʻawale ʻia ʻo Melanin anabolism i nā manawa like ʻole.Manaʻo nā kānaka ʻepekema he hiki ke aʻo i nā mea hana keʻokeʻo a hana no nā manawa metabolic like ʻole.

(1) Ka wā mua o ka hana ʻana o ka melanin

① Hoʻopilikia i ka transcription a / a i ʻole glycosylation o tyrosinase;② Kāohi i nā regulators i ka hoʻokumu ʻana o tyrosinase;③ Ka hoʻomalu ʻana o ka tyrosinase ma hope o ka unuhi ʻana.

(2) Ka wā hoʻohui melanin
Ma ke ʻano o ka enzyme kī a me ka hoʻemi ʻana i ka helu no ka melanin synthesis, ʻo ka tyrosinase inhibitors ke kumu noiʻi a me ka hoʻomohala ʻana i kēia manawa.No ka mea, ʻo ka hapa nui o nā mea keʻokeʻo e like me ka phenol a me nā derivatives catechol e like me ka tyrosine a me ka dopa, ua helu pinepine ʻia nā mea keʻokeʻo i hoʻopaʻa ʻia ma ke ʻano he mea hoʻokūkū ʻole a hoʻokūkū paha o tyrosinase.

(3) Ka pae hope o ka hana ʻana o ka melanin

①Hoʻopau i ka hoʻoili melanosome;nā mea me ka serine protease inhibitory hopena, e like me rwj-50353, pale loa i ka UBV-induced epidermal pigmentation;He hopena keʻokeʻo ʻo ka soybean trypsin inhibitor akā ʻaʻohe hopena i ka ʻona o nā pūnae puaʻa;Niacinamide, hiki ke pale i ka lawe ʻana o nā melanocytes ma waena o nā melanocytes a me nā keratinocytes;② Melanin dispersion a me ka metabolism, α-hydroxy acid, free fatty acid a me retinoic acid, hoʻoulu i ka hana hou o ka cell a hāpai i nā keratinocytes melaninized o ka wehe ʻana.

Pono e hoʻomaopopo ʻia ʻaʻole kūpono ka noiʻi a me ka noi ʻana o nā mea keʻokeʻo e pili ana i ka metabolism melanin i luna no ka pale ʻana a me ka mālama ʻana i nā papa senile.No ka mea pili ka hana o ka hana ʻana o ka senile plaque i ka hoʻokumu ʻana o lipofuscin, hoʻohana mau ʻia nā mea hana antioxidative e hoʻopaneʻe a hoʻohuli i nā plaque senile.
