All the nonprotein amino acids found in the Murchison meteorite are products of the action of electric discharge on a mixture of methane, nitrogen, and water with traces of ammonia. These amino acids include alpha-amino-n-butyric acid, alpha-aminoisobutyric acid, norvaline, isovaline, pipecolic acid, beta-alanine, beta-amino-n-butyric acid, beta-aminoisobutyric acid, gamma-aminobutyric acid, sarcosine, N-ethylglycine, and N-methylalanine. In addition, norleucine, alloisoleucine, N-propylglycine, N-isopropylglycine, N-methyl-beta-alanine, N-ethyl-beta-alanine alpha,beta-diaminopropionic acid, isoserine, alpha,gamma-diaminobutyric acid, and alpha-hydroxy-gamma-aminobutyric acid are produced by the electric discharge, but have not been found in the meteorite.
在默奇森陨石中发现的所有非蛋白质氨基酸都是甲烷、氮气、水与微量氨的混合物在放电作用下产生的产物。这些氨基酸包括α-氨基正丁酸、α-氨基异丁酸、正缬氨酸、异缬氨酸、哌啶酸、β-丙氨酸、β-氨基正丁酸、β-氨基异丁酸、γ-氨基丁酸、肌氨酸、N-乙基甘氨酸和N-甲基丙氨酸。此外，放电还会产生正亮氨酸、别异亮氨酸、N-丙基甘氨酸、N-异丙基甘氨酸、N-甲基-β-丙氨酸、N-乙基-β-丙氨酸、α,β-二氨基丙酸、异丝氨酸、α,γ-二氨基丁酸和α-羟基-γ-氨基丁酸，但在陨石中尚未发现。
