一般說明

尿酸是人类嘌呤降解的最终产物。它是由黄嘌呤氧化酶对黄嘌呤的作用形成。尿酸水平升高在临床上表现为痛风。在除人类以外的物种中，尿酸可进一步代谢。在除灵长类动物以外的哺乳动物中，尿酸可转化为尿囊素。在硬骨鱼中，尿囊素可进一步转化为尿囊酸盐，然后水解成尿素和乙醛酸。尿酸还可用于嘌呤的生物合成。它已被研究用作过氧亚硝基等生物自由基的清除剂。已有相关文献发表了关于尿酸的高效液相色谱（HPLC）和气相色谱-质谱（GC-MS）法。尿酸可促进血管平滑肌细胞中单核细胞趋化蛋白-1（MCP-1）的表达。

應用

尿酸已用于：
  • 制备尿酸钠（MSU）结晶，以研究其对核定位富含亮氨酸重复序列1（NLRP1）基因表达的影响
  • 还原剂，以测试其对正铁肌红蛋白形成的保护能力
  • 制备MSU，以研究其作为Clec12a特异性配体的用途。

Uric Acid in Cell Culture

Uric acid is not a direct additive to any of the classical cell culture media. However, it is present in animal sera. Consequently, uric acid is typically present in complete serum-supplemented classical cell culture systems.
