The kinds and proportions of amino acids formed in two simulated prebiotic experiments or detected in hydrolyzed extracts of three extraterrestrial samples were found to polymerize thermally under various atmospheres or at low pressures. Yields, tested properties, and amino acid compositions of the polymers were not influenced by the type of enveloping atmosphere, including two simulated prebiotic atmospheres and five pure gases. However, polyamino acids prepared at low pressure (0.02, 10(-4) atm) were obtained in appreciably greater yield than those synthesized at 1 atm; amino acid composition was somewhat influenced by low pressure. The results indicate that polyamino acids could have been formed thermally under a variety of possible prebiotic atmospheres and on planetary bodies of low atmospheric pressure.
发现在两个模拟的益生元前实验中形成的或在三个外星样品的水解提取物中检测到的氨基酸种类和比例，在各种大气条件下或低压下会发生热聚合。聚合物的产率、测试性质和氨基酸组成不受包围大气类型的影响，包括两种模拟的益生元前大气和五种纯气体。然而，在低压（0.02、10⁻⁴ 大气压）下制备的聚氨基酸的产率明显高于在1个大气压下合成的产率；氨基酸组成受到低压的一定影响。结果表明，聚氨基酸可能在各种可能的益生元前大气条件下以及在低气压的行星体上通过热作用形成。
