Huahana Huahana
ʻO Isoleucine (i hoʻopau ʻia ʻo Ile a i ʻole I) he ʻakika α-amino me ke ʻano kemika HO2CCH(NH2)CH(CH3)CH2CH3.He waikawa amino koʻikoʻi ia, ʻo ia hoʻi, ʻaʻole hiki i ke kanaka ke synthesize ia, no laila pono e ʻai ʻia.ʻO kāna codons ʻo AUU, AUC a me AUA. Me kahi kaulahao ʻaoʻao hydrocarbon, ua helu ʻia ʻo isoleucine ma ke ʻano he waikawa amino hydrophobic.Me ka threonine, ʻo isoleucine kekahi o nā waikawa amino maʻamau i loaʻa kahi kaulahao ʻaoʻao chiral.ʻEhā stereoisomers o ka isoleucine hiki ke hiki, me ʻelua mau diastereomers o L-isoleucine.Eia nō naʻe, aia ka isoleucine i ke ʻano i loko o kahi ʻano enantiomeric, (2S,3S) -2-amino-3-methylpentanoic acid.
