Lipolysis is the hydrolysis of triglycerides into glycerol and free fatty acids. Lipolysis is induced through activation of beta adrenergic receptors. Isoproterenol/Isoprenaline is a non-selective beta adrenergic agonist structurally similar to adrenaline. By administering isoproterenol ''in vivo'', it is possible to artificially stimulate whole-body lipolysis and assess changes in the concentrations of the products of lipolysis (i.e., glycerol and free fatty acids) in the blood. | Lipolysis is the hydrolysis of triglycerides into glycerol and free fatty acids.
