L-Leucine |61-90-5
Incazelo Yemikhiqizo
I-Leucine (efushanisiwe ngokuthi i-Leu noma i-L) iyi-branched-chainα-amino acid enefomula yamakhemikhali i-HO2CCH(NH2)CH2CH(CH3)2.I-Leucine ihlukaniswa njenge-hydrophobic amino acid ngenxa ye-aliphatic isobutyl side chain.Ifakwe ikhodi ngama-codon ayisithupha (UUA, UUG, CUU, CUC, CUA, kanye ne-CUG) futhi iyingxenye enkulu yama-subunits ku-ferritin, i-astacin namanye amaprotheni 'e-buffer'.I-Leucine iyi-amino acid ebalulekile, okusho ukuthi umzimba womuntu awukwazi ukuyihlanganisa, ngakho-ke, kufanele idliwe.
