Geological conditions play a significant role in prebiotic/abiotic organic chemistry, especially when reactive minerals are present. Previous studies of the prebiotic synthesis of amino acids and other products in mineral‐containing systems have shown that a diverse array of compounds can be produced, depending on the experimental conditions. However, these previous experiments have not simulated the effects of varying geochemical conditions, in which factors such as pH, iron redox state, or chemical concentrations may vary over time and space in a natural environment. In geochemical systems that contain overlapping gradients, many permutations of individual conditions could exist and affect the outcome of an organic reaction network. We investigated reactions of pyruvate and glyoxylate, two compounds that are central to the emergence of metabolism, in simulated geological gradients of redox, pH, and ammonia concentration. Our results show that the positioning of pyruvate/glyoxylate reactions in this environmental parameter space determines the organic product distribution that results. Therefore, the distribution pattern of amino acids and alpha‐hydroxy acids produced prebiotically in a system reflects the specific reaction conditions, and would be distinct at various locations in an environment depending on local geochemistry. This is significant for origin of life chemistry in which the composition and function of oligomers could be affected by the environmentally driven distribution of monomers available. Also, for astrobiology and planetary science where organic distribution patterns are sometimes considered as a possible biosignature, it is important to consider environmentally driven abiotic organic reactions that might produce similar effects.

地球化学和环境参数对氢氧化铁矿物驱动的非生物有机化学的影响

地质条件在益生元/非生物有机化学中起着重要作用，特别是当存在活性矿物质时。先前对含矿物质系统中氨基酸和其他产品的益生元合成的研究表明，取决于实验条件，可以生产出各种各样的化合物。但是，这些先前的实验并未模拟变化的地球化学条件的影响，在自然环境中，pH，铁氧化还原状态或化学浓度等因素可能会随时间和空间而变化。在包含重叠梯度的地球化学系统中，单个条件的许多排列可能存在并影响有机反应网络的结果。我们研究了丙酮酸和乙醛酸的反应，在氧化还原，pH和氨浓度的模拟地质梯度中，两种对代谢产生至关重要的化合物。我们的结果表明，丙酮酸/乙醛酸酯反应在此环境参数空间中的位置决定了所得到的有机产物的分布。因此，系统中由益生元产生的氨基酸和α-羟酸的分布模式反映了特定的反应条件，并且在环境中的不同位置（取决于局部地球化学）会有所不同。这对于生命化学的起源是重要的，在生命化学中，低聚物的组成和功能可能受到环境中可用单体分布的影响。也，
