Aspartic acid an amino acid formed by transamination , in which the amino group of dlutamic acid is transferred to oxaloacetic acid 天冬氨酸：由转氨基作用形成的一种氨基酸，谷氨酸的氨基基团被转移到草酰乙酸中。
2.
The amino group becomes attached to the coenzyme to form pyridoxamine phosphate , and is then transferred to the a - keto acid , which is usually pyruvic acid , oxaloacetic acid , or - ketoglutaric acid 反应中氨基首先连接在辅酶上形成磷酸吡哆氨，然后氨基转移到-酮酸上，这种-酮酸可以为丙酮酸、草酰乙酸或是-酮戊二酸。
3.
In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid , which is transported to the bundle sheath cells , where the carbon dioxide is released , then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate , the first step in the calvin cycle 在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸，这是卡尔文的循环第一步。
