ACHA: Ibikoresho byo kwisiga byimpinduramatwara

ACHA ikomatanyirizwa muri acetylation reaction ya kamereHA. Iyi nzira isimbuza amwe mumatsinda ya hydroxyl muri HA hamwe na acetyl matsinda, biha ACHA nibintu byihariye. Ikintu kigaragara cyane muri ACHA nuburyo bubiri - kamere, kuba hydrophilique na lipofilique. Iyi amphiphilic iranga ACHA kugira isano ikomeye kuruhu. Ntishobora gukurura gusa no kugumana molekile zamazi nka HA gakondo, ariko kandi zinjira cyane muri lipide yuruhu - ibice bikungahaye, bigera ku buryo bwuzuye kandi burambye - burambye.

Ku bijyanye n'ubushuhe,ACHAisumba kure iyayibanjirije, HA. Ubushakashatsi bwerekanye ko ACHA ishobora gukuba kabiri imbaraga za HA. Ihuza vuba n'amazi, ikongerera cyane urwego rwoguhindura uruhu. Mubyukuri, irashobora gutuma uruhu rutobora mumasaha arenga 12, rutanga ubushuhe bwigihe kirekire - gufunga uruhu. Ibi ntibisiga uruhu gusa kumva byoroshye kandi byoroshye ahubwo bifasha no kugabanya kugaragara kumirongo myiza iterwa no gukama.

Kurenza ubushuhe, ACHA nayo igira uruhare runini mugusana inzitizi zuruhu. Itera ikwirakwizwa ry'uturemangingo twa epidermal no gusana ibyangiritse. Mugushimangira imikorere yinzitizi yuruhu karemano, ACHA ifasha kugabanya guhinduka kwamazi yimbere. Ibi ni ingenzi cyane mu kurinda uruhu impungenge z’ibidukikije nko guhumana, imirasire ya UV, n’ikirere kibi. Nkigisubizo, igabanya neza gukama kwuruhu no gukomera, bigatuma uruhu rukomera.

ACHAirerekana kandi imbaraga zikomeye murikurwanya - gusaza. Yongera uruhu rworoshye mugutezimbere umusaruro wa kolagen. Kolagen ni poroteyine y'ingenzi iha uruhu gukomera no gukora neza. Mugihe tugenda dusaza, umusaruro wa kolagen uragabanuka, bigatuma habaho iminkanyari hamwe nuruhu rugabanuka. ACHA irashobora kurwanya iki gikorwa ikangura fibroblast, selile ishinzwe kubyara kolagen, kugirango yongere synthesis. Byongeye kandi, ACHA yasanze igabanya imvugo ya matrix metalloproteinase (MMPs), imisemburo isenya kolagen na elastine mu ruhu. Muguhagarika MMPs, ACHA ifasha kugumana ubusugire bwa matrice idasanzwe yuruhu, bikagira uruhare mukurwanya gusaza.

Byongeye kandi, ACHA ifite ibyiyumvo bishimishije, bidafatika, bigatuma iba ikintu cyiza kubintu byinshi byo kwisiga, harimo essence, masike, amavuta, amavuta yo kwisiga. Gukomera kwayo mumazi nabyo byoroshye kwinjiza muburyo butandukanye. Waba ushaka ibicuruzwa byayobora uruhu rwawe rwumye, gusana inzitizi yuruhu yangiritse, cyangwa kurwanya ibimenyetso byubusaza, ibicuruzwa birimoACHAgishobora kuba igisubizo.

Mu gusoza, ACHA nibintu byimpinduramatwara mubikorwa byo kwisiga. Ihuriro ryihariye ryihariye, uruhu - inzitizi - gusana, hamwe no kurwanya - gusaza bituma biba ngombwa - kugira umuntu wese ushaka ibicuruzwa byiza - byiza, byita ku ruhu. Mugihe ibirango byinshi byo kwisiga bitangiye kwinjiza ACHA mubyo bakora, abaguzi barashobora gutegereza kubona inyungu zidasanzwe zibi bintu bishya.
