Version 2.5
Creation Date 2005-11-16 15:48:42

Common Name Isocitric acid
Description The citrate oxidation to isocitrate is catalyzed by the enzyme aconitase. Human prostatic secretion is remarkably rich in citric acid and low aconitase activity will therefore play a significant role in enabling accumulation of high citrate levels (PubMed ID 8115279)
