The main gluconeogenic precursor in kidney is thought to be lactate; however, less is emphasized enantiomerically. L-lactate is a glycolysis end-product, but D-lactate is formed after detoxification of methylglyoxal, which is the main source of advanced glycation end-products.

乳酸为肾脏糖质新生的主要来源，其含有一不对称碳，故具有D-、L-乳酸两种镜相异构物，而D-、L-乳酸两者之生成相当不同，L-乳酸是糖解作用之终产物，D-乳酸为体内一醣化终产物(advanced glycation end-products)─甲基乙二醛进行去毒化反应所生成，目前缺乏对乳酸镜像异构物与肾脏糖质新生间相关的探讨。
