title: The response of glycated albumin to blood glucose change in the circulation in streptozotocin-diabetic rats--comparison of theoretical values with experimental data.
abstract: The contribution of the preceding blood glucose level to glycated protein was theoretically analyzed using a linear kinetic model and was compared with experiments using streptozotocin-diabetic rats. We assumed that the glycation process can be described by one irreversible step and that the fraction of glycated protein is small. A formula based on these two assumptions showed that the level of glycated protein was proportional to the weighted mean blood glucose concentration in the preceding period and that the weight function was determined by the metabolic characteristics of each protein. For assessing the usefulness of the present formula, the value calculated for the response of glycated albumin (GA) to acute blood glucose change in streptozotocin-diabetic rats was compared with the data obtained under three experimental conditions. The calculated responses of GA showed a little more retardation than the observed data, but showed enough agreement with them.
