On the basis of radioisotope-incorporation experiments it is suggested that acetyl-CoA, an obligatory intermediate in chloroplast terpenoid biosynthesis, may be formed in maize from photosynthetically fixed carbon dioxide by the route carbon dioxide-->glycollate-->glyoxylate-->glycine-->serine-->pyruvate-->acetyl-CoA. The proposed route is supported by conventional radioisotope-dilution studies and by experiments with inhibitors affecting reactions involved in the pathway. The proposed route appears to play little part in formation of extrachloroplastidic sterol.
基于放射性同位素掺入实验，有人提出，叶绿体萜类生物合成过程中必不可少的中间体乙酰辅酶A，在玉米中可能由光合固定的二氧化碳通过以下途径形成：二氧化碳→乙醇酸→乙醛酸→甘氨酸→丝氨酸→丙酮酸→乙酰辅酶A。传统的放射性同位素稀释研究以及使用影响该途径中相关反应的抑制剂进行的实验，均支持了这一提出的途径。该提出的途径似乎在叶绿体外甾体的形成过程中作用不大。
