Carboxylesterase was purified from rat kidney in an electrophoretically homogeneous form by acetone precipitation, followed by successive chromatographies on DEAE-cellulose and hydroxyapatite and then isoelectric focusing. The purified enzyme catalyzed the hydrolyses of monoacylglycerols and short-chain triacylglycerols, such as tributyrin
