Metabolic conversion of l-galactono-1, 4-lactone and l-ascorbic acid to (+)-tartaric acid and oxalic acid has been studied in Pelargonium crispum, cv. Prince Rupert. Experiments with specifically labeled substrates suggest a path of conversion involving cleavage of l-ascorbic acid, or a metabolic product of l-ascorbic acid, between C(2) and C(3), such that oxalic acid arises from the two carbon fragment and (+)-tartaric acid from the four carbon fragment.
在天竺葵(Pelargonium crispum), cv. 鲁珀特亲王品系中研究了 l-半乳糖酸-1,4-内酯和 l-抗坏血酸向(+)-酒石酸和草酸的代谢转化。用特异性标记的底物进行的实验表明,转化途径涉及 l-抗坏血酸或 l-抗坏血酸的代谢产物在 C(2)和 C(3)之间的裂解,使得草酸来自两个碳原子片段,而(+)-酒石酸来自四个碳原子片段。
