ADMET

代谢
醛类物质很容易被氧化成有机酸,而这些有机酸反过来又可以作为脂肪酸氧化途径和克雷布斯循环的底物。醛的氧化由醛脱氢酶催化,该酶在大脑、红细胞、肝脏、肾脏、心脏和胎盘中被发现。
Aldehydes are readily oxidized to organic acids, which, in turn, can serve as substrates for fatty acid oxidation pathways and the Krebs cycle. ... Oxidation of aldehydes is catalyzed by aldehyde dehydrogenase, which has been found in the brain, erythrocytes, liver, kidney, heart, and placenta. /Aldehydes/

代谢
醛类的解毒主要通过以下两条途径进行:(1)氧化生成易于代谢的酸;(2)通过与巯基团的反应使其失活,尤其是与谷胱甘肽的反应。在耗尽谷胱甘肽水平或抑制醛脱氢酶(例如,使用戒酒硫治疗)的情况下,醛类毒性的急性和慢性效应可能会更加充分地表现出来。/醛类/
... The detoxification of aldehydes can be seen to proceed basically via two routes: (1) an oxidation to yield readily metabolized acids; (2) inactivation by reaction with sulfhydryl groups, particularly glutathione. Under conditions that either deplete glutathione levels, or that result in an inhibition of aldehyde dehydrogenase (for example, Antabuse treatment), the acute and chronic effects of aldehyde toxicity might be more fully expressed. /Aldehydes/

制备方法与用途

化学性质
这是一种无色液体,具有强烈的水果甜香气和轻微的清香。其沸点为82~84℃(2000Pa),不溶于水但能溶解于乙醇中。

用途
这种物质被用作食品香料。

生产方法
d-异构体可以通过将d-二氢香茅醇与异丙酯铝酸盐在70~100℃和1862Pa下加热后,再于140~160℃加入桂醛反应而制得。另一种方法是通过在304kPa的压力下,在甲醇中将香茅醛氢化获得。此外,dl-异构体也可以通过在乙醇中以碳酸钯或碳酸锶为催化剂加压氢化柠檬醛来制备。
