Results 1–3 of 3 for izoleucin
isoleucine → izoleucin
Isoleucine is hydrophobic amino acids with aliphatic side chain. It is one of the three amino acids having branched hydrocarbon side chains. The side chains of these amino acids are not reactive but, these residues are critically important for ligand binding to proteins, and play central roles in protein stability. Isoleucine is an essential amino acid, which means that humans cannot synthesize it, so it must be ingested.
- Abbreviations: Ile, I
- IUPAC name: 2-amino-3-methylpentanoic acid
- Molecular formula: C6H13NO2
- Molecular weight: 131.12 g/mol
leucine → leucin
Leucine is hydrophobic amino acids with aliphatic side chain. It has one additional methylene group in its side chain compared with valine. The nonpolar hydrophobic amino acids tend to cluster together within proteins, stabilizing protein structure by means of hydrophobic interactions. Leucine is an essential amino acid, which means that humans cannot synthesize it, so it must be ingested.
- Abbreviations: Leu, L
- IUPAC name: 2-amino-4-methylpentanoic acid
- Molecular formula: C6H13NO2
- Molecular weight: 131.17 g/mol
valine → valin
Valine is hydrophobic amino acids with aliphatic side chain. It is a member of the branched-chain amino acid family, along with leucine and isoleucine. Valine differs from threonine by replacement of the hydroxyl group with a methyl substituent, but they are of roughly the same shape and volume. The nonpolar hydrophobic amino acids tend to cluster together within proteins, stabilizing protein structure by means of hydrophobic interactions. Valine is an essential amino acid, which means that it cannot be synthesized in the body and must be obtained through dietary sources.
- Abbreviations: Val, V
- IUPAC name: 2-amino-3-methylbutanoic acid
- Molecular formula: C5H11NO2
- Molecular weight: 117.15 g/mol
