Citric Acid	Reaction 2: Dehydration of an alcohol Two steps (Rx. 2 and 3) are required to isomerize the position of the -OH group on citric acid. This first step is a dehydration of an alcohol to make an alkene. The cis-aconitic acid remains bound to the enzyme aconitase in readiness for the next step. This reaction is catalyzed by aconitase.	cis-Aconitic Acid
