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 α -amino-n-butyric acid, α -aminoisobutyric acid, norvaline, isovaline, pipecolic acid, β -alanine, β -amino-n-butyric acid, β -aminoisobutyric acid, γ -aminobutyric acid, sarcosine, N-ethylglycine, and N-methylalanine. In addition, norleucine, alloisoleucine, N-propylglycine, N-isopropylglycine, N-methyl-β -alanine, N-ethyl-β -alanine α,β -diaminopropionic acid, isoserine, α,γ -diaminobutyric acid, and α -hydroxy-γ -aminobutyric acid are produced by the electric discharge, but have not been found in the meteorite.
