Isicelo
Apho ulusu oluntsundu lugqalwa njengolunomtsalane, abantu baya beyiqonda ngakumbi imiphumo eyingozi yokukhanya kwelanga nokuba nomhlaza wolusu. Umnqweno wokufumana i-tan ekhangelekayo yendalo ngaphandle kokutshisa ilanga uyakhula. I-Dihydroxyacetone, okanye i-DHA, isetyenziswe ngempumelelo njenge-agent yokuzitshisa ngaphezu kwesiqingatha senkulungwane. Sesona sithako sisebenzayo kuwo onke amalungiselelo okhathalelo lwesikhumba olungenalanga, kwaye sithathwa njengesona songezo sisebenzayo sokungasuki elangeni.
Umthombo weNdalo
I-DHA yi-3-carbon yeswekile ebandakanyekayo kwi-carbohydrate metabolism kwizityalo eziphezulu kunye nezilwanyana ngokusebenzisa inkqubo efana ne-glycolysis kunye ne-photosynthesis. Yimveliso ye-physiologic yomzimba kwaye kucingelwa ukuba ayinayo ityhefu.
Ulwakhiwo lweemolekyuli
I-DHA yenzeka njengomxube we-monomer kunye ne-4 dimers. I-monomer yenziwa ngokufudumeza okanye ukunyibilikisa i-dimeric DHA okanye ngokuyinyibilikisa emanzini. Iikristale ze-monomeric zibuyela kwiifom ze-dimeric ngaphakathi malunga neentsuku ze-30 zokugcinwa kwindawo epholileyo. Ke ngoko, i-DHA eyomeleleyo ibonisa ubukhulu becala kwi-dimeric form.
I-Browning Mechanism
I-Dihydroxyacetone ithambisa ulusu ngokuzibophelela kwii-amines, iipeptides kunye nee-amino acids zasimahla zomaleko wangaphandle we-stratum conrneum ukuvelisa i-Maillard reaction. I-"tan" emdaka ivela kwiiyure ezimbini okanye ezintathu emva kokuba ulusu ludibene ne-DHA, kwaye luyaqhubeka nokuba mnyama malunga neeyure ezintandathu. Isiphumo sisiba se-tan esibonakalayo kwaye kuncipha kuphela xa iiseli ezifileyo zolwele lwe-horney zigqabhuka.
Ukuqina kwetan kuxhomekeke kuhlobo kunye nobukhulu bomaleko ophondo. Apho i-stratum corneum inzima kakhulu (kwiingqiniba, umzekelo), i-tan inamandla. Apho umaleko wophondo ubhityile (njengasebusweni) i-tan iyancipha.
