当用乙酰丙酸处理时，变绿的黄瓜子叶积累δ-氨基乙酰丙酸。将各种特殊标记的化合物应用到组织上，并在δ-氨基乙酰丙酸中测量标记。谷氨酸、谷氨酰胺和α-酮戊二酸与δ-氨基乙酰丙酸的结合程度远大于甘氨酸和琥珀酸。提出了一种新的δ-氨基酮戊酸生物合成路线，其中α-酮戊二酸的碳骨架被完整结合。
Greening cucumber cotyledons accumulate δ-aminolevulinic acid when treated with levulinic acid. A variety of specifically labelled compounds were applied to the tissue and label was measured in the δ-aminolevulinic acid. Glutamate, glutamine and α-ketoglutarate were found to be incorporated into δ-aminolevulinic acid to a much greater extent than were glycine and succinate. A new route of δ-aminolevulinic acid biosynthesis is proposed wherein the carbon skeleton of α-ketoglutarate is incorporated intact.
