An artificial-membrane-bound glycerokinase chosen as a membrane-bound two-substrate-enzyme model has been used to separate two unequal compartments of a specially designed diffusion cell. An interesting feature is the asymmetry of compartments and the existence of a diffusion layer adjacent to

The effects of acylation-stimulating protein (ASP) and insulin on free fatty acid (FFA) release from isolated human fat cells and the signal transduction pathways to induce these effects were studied. ASP and insulin inhibited basal and norepinephrine-induced FFA release by

Cardiovascular complications of obesity are more common in men than women. Sex differences in visceral fat lipolysis may be of importance in this respect, since increased release of free fatty acids (FFAs) from visceral fat to the liver by the

The weight loss achieved during treatment with very-low-calorie diets (VLCD) varies between individuals. The aim of this study was to investigate whether interindividual variations in catecholamine-induced lipolysis are of importance for the rate of weight loss during VLCD. Prospective study.

Upper-body obesity is an important risk factor for developing non-insulin dependent diabetes. To investigate the possibility that a lipolysis defect is present in this form of obesity, we examined the adrenergic regulation of lipolysis in abdominal subcutaneous fat cells from
