Aliphatic (alkane) Amino Acids •Proline(pro, P) – cyclic “imino acid” •Glycine(gly, G)– only non-chiral amino acid, not hydrophobic •Alanine(ala, A) – R- group = methyl-group •Valine(Val, V) – Think V! •Leucine(Leu, L) – •Isoleucine(Ile, I) - 2 chiral carbons HydrophobicityAliphatic (alkane) Amino Acids •Proline(pro, P) – cyclic “imino acid” •Glycine(gly, G)– only non-chiral amino acid, not hydrophobic •Alanine(ala, A) – R- group = methyl-group •Valine(Val, V) – Think V! •Leucine(Leu, L) – •Isoleucine(Ile, I) - 2 chiral carbons Hydrophobicity
