Abstract
Abstract The N-trifluoroacetylmethyl esters were found to yield single peaks on gas chromatography for the amino acids: alanine, valine, isoleucine, leucine, glycine, proline, aspartic acid, threonine, methionine, serine, glutamic acid, phenylalanine, hydroxyproline, and lysine. Improved yields of the derivatives were prepared by the use of sulfonated polystyrene resin in the hydrogen form as a catalyst for the formation of the methyl ester.
