Zur radiationschemischen Bildung von Aminosäuren durch Carboxylierung und Aminierung
- The formation of aliphatic α-amino acids by X-ray induced carboxylation of simple amines or amination of simple carboxylic acids is not favored over the formation of other amino acids. The new carboxylic and amino groups are more or less distributed statistically over the carbon atoms of the starting material. On radiationchemical formation of aliphatic hydrocarbons over C3, therefore, an increasing amount of unusual amino acids is produced. The results are influenced by various parameters such as temperature, pH, concentration, linear energy transfer and total dosis of radiation applied. Also peptides can be formed radiationchemically. However, the formation of greater molecules by radiationchemical processes under the conditions of a primitive earth seems to have only a low probability. The reaction mechanisms of radiationchemical carboxylation and amination are discussed.
