Ufa Wapamwamba wa Amino Acid L-leucine
Mafotokozedwe Akatundu
Leucinendi zofunika amino asidi kuti ntchito mu biosynthesis wa mapuloteni.Leucine ndi α-amino acid, kutanthauza kuti ili ndi gulu la α-amino (lomwe liri mu protonated −NH3+mawonekedwe pansi pa chilengedwe), gulu la α-carboxylic acid (lomwe liri mu deprotonated −COO−kupanga pansi pazikhalidwe zachilengedwe), ndi gulu la mbali la isobutyl, kupangitsa kuti ikhale yopanda polar aliphatic amino acid.Ndikofunikira mwa anthu, kutanthauza kuti thupi silingathe kuzipanga: ziyenera kupezeka kuchokera ku zakudya.Zakudya za anthu ndi zakudya zomwe zimakhala ndi mapuloteni, monga nyama, mkaka, soya, nyemba ndi nyemba zina.Imasungidwa ndi ma code UUA, UUG, CUU, CUC, CUA, ndi CUG.

Ntchito
Leucine ndi amino acid wofunikira pakupanga mapuloteni.Kuphatikiza apo, mofanana ndi ma amino acid ena, mafupa a carbon a leucine angagwiritsidwe ntchito kupanga ATP.Komabe, leucine imathanso kuwongolera njira zingapo zama cell monga kaphatikizidwe ka mapuloteni, kusinthika kwa minofu, ndi metabolism.
