Compartmental and noncompartmentalmodels are used to quantify, from multiple steady-state tracer experiments, glucosekinetics and the effect of insulin upon them. Some aspects of experiment design are discussed. A physiological three-compartment model of glucosekinetics is proposed which provides a new quantitative picture of insulincontrol of glucose metabolism. Noncompartmental modeling is shown to have structural errors which prevent physiological insight. Compartmentalmodels make a better use of the informational content of kinetic data, even if more demanding both in terms of modeling and computational effort and in terms of physiological thinking.

Abstract
Compartmental and noncompartmentalmodels are used to quantify, from multiple steady-state tracer experiments, glucosekinetics and the effect of insulin upon them. Some aspects of experiment design are discussed. A physiological three-compartment model of glucosekinetics is proposed which provides a new quantitative picture of insulincontrol of glucose metabolism. Noncompartmental modeling is shown to have structural errors which prevent physiological insight. Compartmentalmodels make a better use of the informational content of kinetic data, even if more demanding both in terms of modeling and computational effort and in terms of physiological thinking.
