Sodium fluoroacetate (FCH 2CO2Na) is a very toxic molecule that is used as rodentpoison. It is converted enzymatically to fluoroacetyl-CoA and is utilized by citratesynthase to generate (2R,3S)-fluorocitrate. The release of this product is a potentinhibitor of the next enzyme in the TCA cycle. Show the mechanism for theproduction of fluorocitrate and explain how this molecule acts as a competitiveinhibitor. Predict the effect on the concentrations of TCA intermediates.

Question

Sodium fluoroacetate (FCH 2CO2Na) is a very toxic molecule that is used as rodent
poison. It is converted enzymatically to fluoroacetyl-CoA and is utilized by citrate
synthase to generate (2R,3S)-fluorocitrate. The release of this product is a potent
inhibitor of the next enzyme in the TCA cycle. Show the mechanism for the
production of fluorocitrate and explain how this molecule acts as a competitive
inhibitor. Predict the effect on the concentrations of TCA intermediates.
