Kugwiritsa ntchito
Kumene khungu lofufuma limaonedwa kukhala lokongola, anthu akuzindikira mowonjezereka za kuipa kwa kuwala kwa dzuŵa ndi kuopsa kwa khansa yapakhungu. Chikhumbo chofuna kukhala ndi mawonekedwe owoneka bwino osawotchedwa ndi dzuwa chikukulirakulira. Dihydroxyacetone, kapena DHA, yakhala ikugwiritsidwa ntchito bwino ngati chodzipukuta pawokha kwazaka zopitilira theka. Ndilo gawo lalikulu pakukonzekera zosamalira khungu popanda dzuwa, ndipo zimatengedwa kuti ndi zothandiza kwambiri pakuwotcha khungu popanda dzuwa.
Gwero Lachilengedwe
DHA ndi shuga wa 3-carbon yomwe imakhudzidwa ndi metabolism yamafuta m'zomera ndi nyama zapamwamba kudzera munjira monga glycolysis ndi photosynthesis. Ndi mankhwala a physiologic m'thupi ndipo amalingaliridwa kuti alibe poizoni.
Kapangidwe ka Maselo
DHA imapezeka ngati chisakanizo cha monoma ndi 4 dimers. The monomer amapangidwa ndi kutentha kapena kusungunuka dimeric DHA kapena kusungunuka m'madzi. Makhiristo a monomeric amabwerera ku mawonekedwe a dimeric mkati mwa masiku pafupifupi 30 atasungidwa m'chipinda chozizira. Chifukwa chake, DHA yolimba imapezeka makamaka mu mawonekedwe a dimeric.
The Browning Mechanism
Dihydroxyacetone imatsuka khungu pomanga ma amines, peptides ndi ma amino acid aulere akunja kwa stratum conrneum kuti apange Maillard reaction. "Tani" wa bulauni umapezeka mkati mwa maola awiri kapena atatu khungu lakhudza DHA, ndipo limakhala mdima kwa maola asanu ndi limodzi. Zotsatira zake zimakhala zotentha kwambiri ndipo zimacheperachepera pomwe ma cell akufa a horney layer amatuluka.
Kuchuluka kwa nyangazi kumadalira mtundu ndi makulidwe a nyangazo. Kumene stratum corneum ndi wandiweyani kwambiri (pazigono, mwachitsanzo), tani ndi lolimba. Kumene nyanga yosanjikiza ya nyanga imakhala yopyapyala (monga pankhope) kutentha kumakhala kochepa kwambiri.
