Khoom Taw Qhia

Leucine (hais cov npe uas yog l) yog ib ceg - Am6 1}}}} kua qaub nrog cov tshuaj forsulula ho2cch (nh2) 2. Leucine yog cais raws li hydrophobic amino acid vim nws cov aliphatic isobutyl sab saw. Nws yog encoded los ntawm rau codons (Uua, Uug, CUL, CUH, CUU Leucine yog ib qho tseem ceeb amino acid, txhais tau tias tib neeg lub cev tsis tuaj yeem cuam tshuam nrog nws, thiab nws yog li ntawd yuav tsum tau muab cov zaub mov ntxiv. e

L - Leucine yog ib qho ntawm yim cov amino acids uas tseem ceeb, thiab tab tom ntawm cov aliphatic cov amino acids nyob rau hauv nees nkaum hom protein. L - leecine thiab l - isoleucine thiab l} valine yog hu peb ceg saw cov amino acids. L - lucineleucine thiab d - leucine yog enantiomers.
