| Abstract | ||||
| The specific activities of two molybdenum hydroxylases; aldehyde oxidase and xanthine oxidase from six tissues; (heart, jejunum, kidney, liver, lung and spleen), of the Arabian one–humped camel, (Camelus dromedarius) were measured. Three different substrates: 3-methylisoquinoline, phthalazine and phenanthridine were used for aldehyde oxidase activity. Only liver had aldehyde oxidase activity with phenanthridine as a substrate. Xanthine oxidase showed no activity in all the studied tissues, with xanthine as a substrate. The values of both Vmax and Km were determined, for hepatic aldehyde oxidase. The activity of aldehyde oxidase was completely inhibited using menadione and hydralazine. | ||||
