Porogaramu
Aho uruhu rw'umuhondo rufatwa nk'urukurura abantu, abantu bagenda barushaho gusobanukirwa ingaruka mbi z'izuba ndetse n'ibyago byo kurwara kanseri y'uruhu. Icyifuzo cyo kugira ibara ry'umuhondo risanzwe ritari ku zuba kirimo kwiyongera. Dihydroxyacetone, cyangwa DHA, imaze imyaka irenga mirongo itanu ikoreshwa neza nk'ikintu cyikora ku ruhu. Ni cyo kintu cy'ingenzi mu bikoresho byose byo kwita ku ruhu bidakoresha izuba, kandi gifatwa nk'inyongera nziza cyane mu ruhu rudakoresha izuba.
Isoko karemano
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 Molekile
DHA ibaho nk'uruvange rwa monomer na dimer 4. Monomer ikorwa no gushyushya cyangwa gushonga dimeric DHA cyangwa kuyishongesha mu mazi. Uduce twa monomeric dusubira mu mafomu ya dimeric mu minsi 30 nyuma yo kubibika mu cyumba kiri mu bushyuhe. Kubwibyo, DHA ikomeye igaragara cyane mu mafomu ya dimeric.
Uburyo bwo Gusiga Ibara ry'Umutuku
Dihydroxyacetone ihindura uruhu uruhu iruhuza na amine, peptides na aside amine zifunguye zo mu gice cyo hanze cya stratum conrneum kugira ngo ikore Maillard reaction. "Umutuku" w'umukara ubaho mu masaha abiri cyangwa atatu nyuma y'uko uruhu rugeze kuri DHA, kandi ugakomeza kwijima mu gihe cy'amasaha agera kuri atandatu. Ibi bivamo umutuku ukomeye kandi ugabanuka gusa iyo uturemangingo twapfuye tw'ururabo rw'imisemburo tuvuyeho.
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.
