The question was amino acids, not chains that make whole things. I shall name all 20. in order of hydrophobic aliphatic, hydrophobic aromatic, basics and acidic polar and the last three my special ones. Alanine, Valine, Leucine, Isoleucine, Methione, Phenylalanine, Tyrosine, Tryptophan, Lysine, Arganine, Histadine, Glutamate, Aspartate, Serine, Threonine, Asparagine, Glutamine, Glycine, Proline, Cystine. Satisfied? If I am wrong, name your amino acids.
