Umgangatho ophezulu we-Amino Acid Powder L-leucine
Ingcaciso yeMveliso
Leucineyi-amino acid ebalulekileyo esetyenziswa kwi-biosynthesis yeeprotheni.I-Leucine yi-α-amino acid, oku kuthetha ukuba iqulethe iqela le-α-amino (elikwi-protonated −NH3+ifom phantsi kweemeko zebhayoloji), iqela le-α-carboxylic acid (ekwi-deprotonated −COO−ifom phantsi kweemeko zebhayoloji), kunye neqela le-isobutyl chain chain, liyenza i-non-polar aliphatic amino acid.Ibalulekile ebantwini, oku kuthetha ukuba umzimba awukwazi ukuyidibanisa: kufuneka ifunyenwe ekutyeni.Imithombo yokutya yabantu kukutya okuneprotheyini, efana nenyama, iimveliso zobisi, iimveliso zesoya, iimbotyi kunye nezinye iimbotyi.Ifakwe ngekhowudi ngeekhowudi UUA, UUG, CUU, CUC, CUA, kunye neCUG.

Umsebenzi
I-Leucine yi-amino acid ebalulekileyo kwi-protein synthesis.Ukongezelela, ngokufanayo nezinye i-amino acids, i-carbon skeleton ye-leucine ingasetyenziselwa ukuvelisa i-ATP.Nangona kunjalo, i-leucine inokulawula iinkqubo ezininzi zeselula ezifana neprotein synthesis, ukuvuselelwa kwezicubu, kunye nemetabolism.
