Amino acid analysis : Hydrolysis, ion-exchange cleanup, derivatization, and quantitation by gas—liquid chromatography
TL;DR: The use of ultrasonication to remove dissolved air while pulling a vaccumm on the sample solution prior to hydrolysis assured a good recovery for methionine and cystine as discussed by the authors.
Journal ArticleDOI
Enantiomer labelling, a method for the quantitative analysis of amino acids
TL;DR: The accuracy of amino acid analysis by enantiomer labelling is equal or superior to that of hitherto known methods.
Journal ArticleDOI
Amino-acids, Aliphatic and Aromatic Hydrocarbons in the Murchison Meteorite
TL;DR: The Murchison meteorite, a type III carbonaceous chondrite, contains substantial amounts of amino-acids, predominantly cyclic aliphatic hydrocarbons, which are consistent with the appreciable content of carbon and nitrogen of this meteorite.
