ABSTRACT
A simple one-step method employing potassium persulphate as an oxidising agent in presence of catalyst, Ag2+, for the oxidation of beta-hydroxybutyrate (beta-OHB) to acetoacetate (AcAc) has been developed and standardized. Under the condition of assay, beta-OHB (0.079-0.395 microM) was quantitatively transformed to AcAc. The reaction linearity was observed from 0.079 to 0.634 microM. Optimum conditions were pH, 6.2; temp., 40 degrees C; persulphate saturation, 40% and catalyst, 1.82 mM. Under the experimental condition, no reversal of inhibition caused by chloride (22.96 mM) was observed at Ag+ concentrations (9.09 and 18.18 mM), while higher conc. of Ag+ (27.27 mM) caused significant reversal of inhibition (about 60%). The maximum reversal of inhibition was achieved at Ag+ (36.36 mM). The level of ketone bodies, when estimated by the present method, was greatly enhanced during starvation period and about 2- and 12-fold higher level of ketone bodies was observed (compared to control) in rats fasted for 24 and 48 hr respectively.
