Isicelo
Lapho isikhumba esinsundu sibhekwa njengesikhangayo, abantu baya ngokuya beqaphela imiphumela eyingozi yokukhanya kwelanga kanye nengozi yomdlavuza wesikhumba. Isifiso sokuba nesikhumba esinsundu esibukeka njengemvelo ngaphandle kokushiswa yilanga siyakhula. I-Dihydroxyacetone, noma i-DHA, isetshenziswe ngempumelelo njenge-ejenti yokuzishiswa yilanga iminyaka engaphezu kwengu-50. Iyisithako esiyinhloko esisebenzayo kuzo zonke izithako zokunakekelwa kwesikhumba ezingenalanga, futhi ibhekwa njengesithako esisebenza kahle kakhulu sokushisa isikhumba esingenalanga.
Umthombo Wemvelo
I-DHA ingushukela one-carbon ezintathu ohilelekile ekugayweni kwama-carbohydrate ezitshalweni nasezilwaneni eziphakeme ngenqubo efana ne-glycolysis kanye ne-photosynthesis. Ingumkhiqizo womzimba womzimba futhi kucatshangwa ukuthi awunabo ubuthi.
Isakhiwo sama-molecular
I-DHA yenzeka njengengxube ye-monomer nama-dimer angu-4. I-monomer yakhiwa ngokushisa noma ukuncibilikisa i-dimeric DHA noma ngokuyincibilikisa emanzini. Amakristalu e-monomeric abuyela ezimeni ze-dimeric zingakapheli izinsuku ezingu-30 zokugcinwa endaweni epholile yegumbi. Ngakho-ke, i-DHA eqinile ivela kakhulu ngesimo se-dimeric.
Indlela Yokwenza I-Browning
I-Dihydroxyacetone ishintsha umbala wesikhumba ngokubopha kuma-amine, ama-peptide kanye nama-amino acid amahhala ezingqimbeni zangaphandle ze-stratum conrneum ukuze ikhiqize ukusabela kwe-Maillard. “I-tan” ensundu yakheka zingakapheli amahora amabili noma amathathu ngemuva kokuthi isikhumba sithinte i-DHA, futhi iyaqhubeka nokuba mnyama cishe amahora ayisithupha. Umphumela uba i-tan ebonakalayo futhi iyancipha kuphela njengoba amangqamuzana afile e-horney layer ephuma.
Ukuqina kombala wesikhumba kuncike ohlotsheni kanye nobukhulu bengqimba yesikhumba. Lapho i-stratum corneum ijiyile kakhulu (ezindololwaneni, isibonelo), umbala wesikhumba uba mkhulu. Lapho ungqimba lwesikhumba lwesikhumba luncane (njengasebusweni) umbala wesikhumba uba mkhulu kancane.
