A comparison of an enzymatic and a gas-chromatographic method for measuring the acetate concentration in the blood plasma of cattle.

The concentration of acetate in blood plasma was measured by both a gas-liquid chromatographic method and an enzymatic method using acetyl-CoA synthetase. When acetate was measured enzymatically without previous protein precipitation, the apparent concentration was lower than when the concentration measured by either a gas-chromatographic method or by the enzymatic method after protein precipitation with perchloric acid and neutralization.
