摘要: Abstract The δ 13 C values of thirty-four individual amino acids and two pyridine carboxylic have been obtained fromthe Murchison meteorite. They were found to range from +4.9 +52.8‰, with statistically significant differences observed both within between acid subgroups. content α-amino declines increasing chain length, a trend similar the ones previously for alkanes. Also 2-methyl-2-amino be heavier in than corresponding 2-H homologues. The3-, 4-, 5-amino do not show comparable declining neither dicarboxylic acids. This variability can interpreted as indicate that synthetic histories soluble organics meteorites may diverse even groups compounds very functional group composition.
