Trace amounts of glycine, serine, and alanine were detected in the carbonate component of the martian meteorite ALH84001 by high-performance liquid chromatography. The detected amino acids were not uniformly distributed in the carbonate component and ranged in concentration from 0.1 to 7 parts per million. Although the detected alanine consists primarily of the L enantiomer, low concentrations (<0.1 parts per million) of endogenous D-alanine may be present in the ALH84001 carbonates. The amino acids present in this sample of ALH84001 appear to be terrestrial in origin and similar to those in Allan Hills ice, although the possibility cannot be ruled out that minute amounts of some amino acids such as D-alanine are preserved in the meteorite.
通过高效液相色谱法在火星陨石ALH84001的碳酸盐成分中检测到了痕量的甘氨酸、丝氨酸和丙氨酸。检测到的氨基酸在碳酸盐成分中分布并不均匀,浓度范围为百万分之0.1至7。虽然检测到的丙氨酸主要由L型对映体组成,但在ALH84001碳酸盐中可能存在低浓度(<百万分之0.1)的内源性D-丙氨酸。ALH84001这个样本中存在的氨基酸似乎源自地球,与艾伦山冰层中的氨基酸相似,不过也不能排除陨石中保存有极少量某些氨基酸(如D-丙氨酸)的可能性。
