摘要
A glycine/(NH(4))(2)SO(4) mixture was isolated by treatment of glyoxylic acid with FeSO(4) and aqNH(3) in H(2)O. The yields of glycine were estimated by (1)H NMR. Pyruvic acid was not reduced to alanine under these conditions. This method for forming glycine might have occurred prebiotically alongside the Urey-Miller arc discharge method for making amino acids because glyoxylic acid is formed by arc discharge through a N(2)/CO(2) atmosphere and both NH(3) and Fe(II) occurred in the earth's early oceans. The carboxylic acid directs the reduction of 2,4-dinitrobenzoic acid to give 2-amino-4-nitrobenzoic acid.
