Homogenized rat livers were extracted with organic solvents and the extracts converted into more readily volatile derivatives (trimethylsilylmethyl esters and permethyl esters). Combined g.l.c.-mass-spectrometric analysis identified the presence of tetraiodothyroformate. It is postulated that mitochondrial beta-oxidation of tetraiodothyropyruvate results in the formation of this apparently undescribed metabolite.

大鼠肝脏中3,3'，5,5'-四碘甲甲酸的鉴定。

用有机溶剂提取均质的大鼠肝脏，并将提取物转化为易挥发的衍生物（三甲基甲硅烷基甲基酯和全甲酯）。组合的glc-质谱分析确定了四碘甲酸酯的存在。据推测，四碘甲状腺丙酮酸的线粒体β-氧化作用导致形成了这种表面上未描述的代谢物。
