Through suppression of the aconitase enzyme in the tricarboxylic acid cycle, aconitase, fluoroacetate is extremely hazardous to humans and other mammals.
'Lethal synthesis' of an isomer of fluor citrate is the cause. fluoroacetate is present in many different plant species, and ruminant animals can die from ingesting them consists of aconitase.
With the chemical formula FCH 2 CO 2 Na, sodium fluoroacetate is an organofluoride. The taste of this colorless salt, which is utilized as a metabolic toxin, is comparable to that of sodium chloride. Potassium and sodium salts are both derived from fluor acetic acid. In 1942, a report on the efficiency of sodium fluoroacetate as a rodenticide was published.
