Isicelo

Lapho isikhumba esibomvu sibhekwa njengesikhangayo, abantu baya ngokuya beqaphela imiphumela eyingozi yokukhanya kwelanga kanye nengozi yomdlavuza wesikhumba. Isifiso sokuthola i-tan ebukeka yemvelo ngaphandle kokushiswa yilanga siyakhula. I-Dihydroxyacetone, noma i-DHA, isetshenziswe ngempumelelo njenge-ejenti yokuzikhukhumeza isikhathi esingaphezu kwengxenye yekhulunyaka. Kuyisithako esiyinhloko esisebenzayo kuwo wonke amalungiselelo okunakekelwa kwesikhumba ngaphandle kwelanga, futhi kuthathwa njengesithasiselo esisebenza kahle kakhulu sokushukwa elangeni.

Umthombo Wemvelo

I-DHA iwushukela onekhabhoni engu-3 obandakanyeka kumetabolism ye-carbohydrate ezitshalweni eziphakeme nasezilwaneni ngenqubo efana ne-glycolysis ne-photosynthesis. Kungumkhiqizo we-physiologic womzimba futhi kucatshangwa ukuthi awunabo ubuthi.

Isakhiwo samangqamuzana

I-DHA yenzeka njengengxube ye-monomer kanye nama-4 dimers. I-monomer yakhiwa ngokushisa noma ukuncibilikisa i-DHA ye-dimeric noma ngokuyincibilikisa emanzini. Amakristalu e-monomeric abuyela kumafomu e-dimeric phakathi nezinsuku ezingaba ngu-30 zokulondoloza endaweni epholile. Ngakho-ke, i-DHA eqinile iveza ngokuyinhloko ngesimo se-dimeric.

I-Browning Mechanism

I-Dihydroxyacetone ithambisa isikhumba ngokubopha ama-amine, ama-peptide nama-amino acid amahhala ezingxenyeni zangaphandle ze-stratum conrneum ukuze enze ukusabela kwe-Maillard. I-"tan" ensundu iba phakathi kwamahora amabili noma amathathu ngemuva kokuthi isikhumba sithinte i-DHA, futhi iyaqhubeka nokuba mnyama cishe amahora ayisithupha. Umphumela uba tan obonakalayo futhi unciphe kuphela lapho amaseli afile ongqimba lwezinyosi ehlakazeka.

Ukuqina kwe-tan kuncike ohlotsheni nokuqina kongqimba olunezimpondo. Lapho i-stratum corneum iminyene kakhulu (ngokwesibonelo, ezindololwaneni), i-tan ishubile. Lapho ungqimba lwezinyosi luzacile (njengasebusweni) ukubanda akubi kakhulu.
