L-Valine |72-18-4
Incazelo Yemikhiqizo
I-Valine (efushanisiwe ngokuthi i-Val noma i-V) iyi-α-amino acid enefomula yamakhemikhali ethi HO2CCH(NH2)CH(CH3)2.I-L-Valine ingenye yama-amino acid angama-20 e-proteinogenic.Amacodon ayo yi-GUU, GUC, GUA, kanye neGUG.Le amino acid ebalulekile ihlukaniswa njenge-nonpolar.Imithombo yokudla yabantu yinoma yikuphi ukudla okunamaprotheni okufana nenyama, imikhiqizo yobisi, imikhiqizo ye-soy, ubhontshisi kanye nemifino.Kanye ne-leucine ne-isoleucine, i-valine iyi-amino acid e-branched-chain.Iqanjwe nge-valerian yesitshalo.Esifweni se-sickle-cell, i-valine ithatha indawo ye-hydrophilic amino acid glutamic acid ku-hemoglobin.Ngenxa yokuthi i-valine i-hydrophobic, i-hemoglobin ijwayele ukuhlangana okungavamile.
