代谢
进行了一项研究,以确定挥发性烃类化合物,如丙烷、正丁烷和异丁烷,是否在小鼠体内被代谢。在吸入这些气体的小鼠中,从丙烷中产生了异丙醇和丙酮,从正丁烷中产生了sec-丁醇和甲基乙基甲酮,从异丁烷中产生了tert-丁醇作为相应的代谢物。此外,发现肝微粒体含有参与这些代谢的酶系统。体外反应表明,肝微粒体可以将丙烷转化为异丙醇,将正丁烷转化为sec-丁醇,将异丁烷转化为tert-丁醇。据推测,烃类化合物首先被微粒体酶系统转化为(omega-1)-醇,然后通过醇脱氢酶转化为相应的酮。
A study was conducted to establish whether volatile hydrocarbons, such as propane, n-butane and iso-butane, are metabolized in mice or not. In mice having inhaled these gases, isopropanol and acetone were yielded from propane, sec-butanol and methyl ethyl ketone from n-butane, and tert-butanol from iso-butane as the respective metabolites. In addition, liver microsomes were found to contain the enzymic system participating in these metabolisms. In vitro reactions with liver microsomes produced isopropanol from propane, sec-butanol from n-butane, and tert-butanol from iso-butane. It was assumed that hydrocarbons were first converted to (omega-1)-alcohols by microsomal enzyme system and then to corresponding ketones by alcohol dehydrogenase.
