The enzyme activities involved in fructose metabolism were measured in human intestine mucosa. Mucosa of the following gut sections were used: duodenum, jejunum, jejunum in the region of the flexura duodenojejunalis, jejunum distal region, ileum middle region and ileum in the region of the valvula ileo coecalis. Ketohexokinase, aldolase, alcohol dehydrogenases NAD- and NADP- dependent were found in all gut sections. The activity of aldehyde dehydrogenase was low in all sections tested. Triokinase could be found only in the duodenum and jejunum region and was absent in the ileum. Glycerate kinase was not present in the human intestine mucosa.
在人肠黏膜中测定了参与果糖代谢的酶活性。使用了以下肠道节段的黏膜：十二指肠、空肠、十二指肠空肠曲区域的空肠、空肠远端区域、回肠中部区域以及回盲瓣区域的回肠。在所有肠道节段均发现了酮己糖激酶、醛缩酶、依赖NAD和NADP的醇脱氢酶。在所测试的所有节段中，醛脱氢酶的活性都很低。磷酸丙糖激酶仅在十二指肠和空肠区域可检测到，而在回肠中不存在。甘油酸激酶在人肠黏膜中不存在。
