Tetrahydrofolic acid and formaldehyde are key human metabolites but their physiologically relevant chemistry is undefined. Our NMR studies confirm formaldehyde as a product of tetrahydrofolic acid degradation but also reveal their reaction regulates the stability of tetrahydrofolic acid. These observations identify a novel non-enzymatic feedback mechanism regulating formaldehyde and folate metabolism that has important implications for folate-targeting chemotherapy in cancer and other diseases.
四氢叶酸和甲醛是关键的人体代谢物，但它们在生理相关条件下的化学反应尚未明确。我们的 NMR 研究证实了甲醛是四氢叶酸降解的产物，但也揭示了它们的反应调节了四氢叶酸的稳定性。这些观察结果确定了一种新的非酶反馈机制，调节甲醛和叶酸代谢，这对癌症和其他疾病中针对叶酸的化疗具有重要意义。
