Effects of menadione and vitamin K 5 on glucose metabolism, respiration, lipolysis, cyclic 3',5'-adenylic acid accumulation, and adenyl cyclase in white fat cells.“An increase of about 4-fold in the solubility of menadione with 0.1 m dihydroxypropyl theophylline was observed at 30 degrees C. Thermodynamic paremeters were calculated by conducting the experiments at different temperatures.”
