Porogaramu
Aho uruhu rwanduye rufatwa nkaho rushimishije, abantu bagenda barushaho kumenya ingaruka mbi zumucyo wizuba hamwe ningaruka za kanseri yuruhu. Icyifuzo cyo kubona igituba gisanzwe kitarimo izuba. Dihydroxyacetone, cyangwa DHA, yakoreshejwe neza nkumuntu wigenga wenyine mugihe kirenga igice cyikinyejana. Nibyingenzi byingenzi mubikorwa byose byo gutunganya uruhu rutagira izuba, kandi bifatwa nkibintu byongera izuba bitagira izuba.
Inkomoko Kamere
DHA ni isukari ya karubone 3 ikora mu mikorere ya karubone mu bimera no mu nyamaswa binyuze mu nzira nka glycolysis na fotosinthesisi. Ni umusaruro w’umubiri kandi bivugwa ko nta burozi urimo.
Imiterere ya molekulari
DHA ibaho nkuruvange rwa monomer na dimim 4. Monomer ikorwa no gushyushya cyangwa gushonga dimeric DHA cyangwa kuyishonga mumazi. Kirisiti ya monomeric isubira muburyo bwa dimeric mugihe cyiminsi 30 yo kubika mubyumba bituje. Kubwibyo, DHA ikomeye cyane yerekana muburyo bwa dimeric.
Uburyo bwa Browning
Dihydroxyacetone ibyina uruhu ihuza amine, peptide na aside amine yubusa ya layer yo hanze ya stratum conrneum kugirango itange Maillard reaction. “Tan” yijimye ikora mumasaha abiri cyangwa atatu nyuma yo guhura nuruhu DHA, kandi ikomeza kwijimye mugihe cyamasaha atandatu. Igisubizo nigitereko gifatika kandi kigabanuka gusa nkuko selile zapfuye zurwego rwa horni zigenda.
Ubukana bw'ibara ry'umukara buterwa n'ubwoko n'ubugari bw'urwego rw'ibara ry'umukara. Aho stratum corneum ari nini cyane (urugero ku nkokora), ibara ry'umukara riba rikomeye cyane. Aho urwego rw'ibara ry'umukara ari ruto (nk'uko bimeze ku maso), ibara ry'umukara riba rito cyane.
