Daim Ntawv Thov
Qhov twg cov tawv nqaij uas muaj xim av raug suav hais tias zoo nkauj, tib neeg tab tom paub ntau ntxiv txog cov teebmeem tsis zoo ntawm lub hnub ci thiab qhov kev pheej hmoo ntawm mob qog noj ntshav ntawm daim tawv nqaij. Kev xav tau kom tau txais xim av zoo li ntuj yam tsis tau pw hauv tshav ntuj tab tom loj hlob tuaj. Dihydroxyacetone, lossis DHA, tau siv tau zoo ua tus neeg sawv cev rau kev tanning tus kheej tau ntau tshaj ib nrab xyoo pua. Nws yog cov khoom xyaw tseem ceeb hauv txhua yam kev npaj khoom siv rau kev tanning tsis muaj hnub ci, thiab suav hais tias yog cov khoom siv tanning tsis muaj hnub ci zoo tshaj plaws.
Qhov Chaw Ntuj
DHA yog ib qho suab thaj uas muaj 3-carbon uas koom nrog kev ua cov carbohydrate hauv cov nroj tsuag thiab tsiaj txhu los ntawm cov txheej txheem xws li glycolysis thiab photosynthesis. Nws yog ib yam khoom ntawm lub cev thiab xav tias tsis muaj tshuaj lom.
Cov Qauv Molecular
DHA tshwm sim los ntawm kev sib xyaw ntawm monomer thiab 4 dimers. Lub monomer yog tsim los ntawm kev ua kom sov lossis yaj dimeric DHA lossis los ntawm kev yaj nws hauv dej. Cov monomeric crystals rov qab mus rau cov qauv dimeric hauv li 30 hnub ntawm kev khaws cia ntawm chav tsev kub. Yog li ntawd, cov khoom khov DHA feem ntau tshwm sim hauv daim ntawv dimeric.
Lub Mechanism Browning
Dihydroxyacetone ua rau daim tawv nqaij daj los ntawm kev khi rau cov amines, peptides thiab cov amino acids dawb ntawm cov txheej sab nraud ntawm stratum conrneum los tsim cov tshuaj tiv thaiv Maillard. Xim av "tan" tshwm sim hauv ob lossis peb teev tom qab daim tawv nqaij kov DHA, thiab txuas ntxiv tsaus ntuj li rau teev. Qhov tshwm sim yog xim av tseem ceeb thiab ploj mus tsuas yog thaum cov hlwb tuag ntawm cov txheej horney poob tawm.
Qhov tawv nqaij daj ntseg nyob ntawm seb hom thiab tuab ntawm cov txheej tawv nqaij kub npaum li cas. Qhov twg cov stratum corneum tuab heev (piv txwv li ntawm lub luj tshib), qhov tawv nqaij daj ntseg yuav kub heev. Qhov twg cov txheej tawv nqaij daj ntseg nyias (xws li ntawm lub ntsej muag) qhov tawv nqaij daj ntseg yuav tsis kub heev.
