L-Isoleucine | 73-32-5
Awọn ọja Apejuwe
Isoleucine (ti a pe ni Ile tabi I) jẹ α-amino acid pẹlu agbekalẹ kemikali HO2CCH (NH2) CH (CH3) CH2CH3. O jẹ amino acid pataki, eyiti o tumọ si pe eniyan ko le ṣepọ, nitorinaa o gbọdọ jẹ. Awọn codons rẹ jẹ AUU, AUC ati AUA.Pẹlu ẹwọn ẹgbẹ hydrocarbon kan, isoleucine jẹ ipin bi amino acid hydrophobic kan. Paapọ pẹlu threonine, isoleucine jẹ ọkan ninu awọn amino acid meji ti o wọpọ ti o ni ẹwọn ẹgbẹ chiral. Awọn stereoisomer mẹrin ti isoleucine ṣee ṣe, pẹlu awọn diastereomers meji ti o ṣeeṣe ti L-isoleucine. Sibẹsibẹ, isoleucine ti o wa ninu iseda wa ni fọọmu enantiomeric kan, (2S,3S) -2-amino-3-methylpentanoic acid.
