Abstract
Mixtures of amino acids were reacted witha-dicarbonyl compounds and the degradation rates were determined. The basic and hydroxy amino acids reacted strongly, the acidic and nonpolar amino acids less so. Variation of the reaction conditions as well as comparing the pk-values of thea-amino groups with the degradation rates showed that mainly substituents on thea-carbon atom and further functional groups were responsible for the reactivity of the amino acids. Aminosäuren wurden im Gemisch mita-Dicarbonylverbindungen umgesetzt und die Abbauraten bestimmt. Die basischen und Hydroxyaminosäuren sowie Glycin reagierten stark, die sauren und apolaren Aminosäuren relativ schwach. Veränderung der Versuchsbedingungen sowie Vergleich der Abbauraten mit den pK-Werten dera-Aminogruppen zeigten, daß in erster Linie Substituenten ama-C-Atom und weitere funktionelle Gruppen für die Reaktivität der Aminosäuren verantwortlich sind.Keywords
