In this work extensive misconceptions of university students' —from nutrition area— about the metabolism of carbohydrates (CHM) in the human organism have been documented. The results lead to consider their difficulties concerning the learning of a complex set of imbricated biochemical models involved. Pursuant to these considerations, three physiological models are proposed as conceptual axes around which CHM in the human organism could be taught, in order to avoid fragmentation in students' knowledge and to give simple physiological contexts where to integrate those biochemical models. These contexts are: (a) a physiological model of the carbon cycle, (b) a physiological model of blood glucose uptake and homeostasis, and (c) a physiological model of the availability of small metabolites.

三种生理模型对于碳水化合物代谢教学的重要性

在这项工作中，记录了来自营养领域的大学生对人体有机体中碳水化合物（CHM）代谢的广泛误解。结果导致考虑他们在学习所涉及的一组复杂的叠瓦生化模型方面的困难。根据这些考虑，提出了三个生理模型作为概念轴，围绕这些模型可以教授人体有机体的 CHM，以避免学生知识的碎片化，并提供简单的生理背景来整合这些生化模型。这些背景是：（a）碳循环的生理模型，（b）血糖摄取和稳态的生理模型，以及（c）小代谢物可用性的生理模型。
