高中生物课本(甲、乙两种)在脂类代谢的课文中,谈到“……这些吸收进来的脂类可以发生以下四种变化,……三是再分解成甘油和脂肪酸等,然后直接氧化分解成二氧化碳和水,或者转变为肝糖原。”我在教学实践中发现,这样的提法容易造成误解。因为这段叙述,给人的印象是脂肪在人体内能够转变成糖类,并由此而引起一系列的片面认识。所以有必要加以澄清。 In high school biology textbooks (A and B), in the lipid metabolism text, we talked about “... These four lipids that can be absorbed can take the following four changes.... The third is to decompose glycerin and fatty acids, and then directly Oxidative decomposition into carbon dioxide and water, or into liver glycogen." I found in teaching practice, this formulation is prone to misunderstanding. Because of this narrative, it gives the impression that fat can be converted into sugar in the human body, and this leads to a series of one-sided understanding. So it is necessary to clarify.
