A prebiotic synthesis of the nucleobase orotate, and the citric acid cycle intermediate pyruvate, proceeds in a single pot from two small glycine derivatives, hydantoin and glyoxylate, under mild aqueous conditions. These findings support a co-evolution of pathways to core protometabolites and nucleic acid building blocks in a common environment. Additionally, open-chain thiohydantoin derivatives enable
核碱基乳清酸盐和柠檬酸循环中间体丙酮酸盐的益生元合成是在温和的水性条件下,由两种小甘氨酸衍生物(乙内酰脲和乙醛酸盐)在一个锅中进行的。这些发现支持在共同环境中核心原代谢物和核酸构建模块的途径的共同进化。此外,开链硫代乙内酰脲衍生物能够合成硫代乳清酸核苷。
