The product chorismate of this pathway is precursor to the synthesis of the aromatic amino acids phenylalanine , tyrosine , and tryptophan as well as other essential aromatic secondary metabolites such as ubiquinone , menaquinone and vitamin k . phosphoenolpyruvate and shikimate 3 - phophate are converted to 5 - enolpyruvlshimimate - 3 - phosphate and phosphate 芳香族氨基酸苯丙氨酸、酪氨酸、色氨酸和其它一些必需代谢物如泛醌、维生素k2类、维生素k的起始物是莽草酸途径所产生的分枝酸。

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。

Glyphosate is a foliar applied , broad spectrum , post - emergence herbicide capable of controlling annual and perennial grasses and dicotyledonous weeds . due to the similarity structure between glyphosate and phosphoenolpyruvate , glyphosate can inhibit epsp synthase by rivalrously uniting epsp synthase with phosphoenolpyruvate 草甘膦是一种施用于叶片的、广谱的、非选择性的、后现性的有机磷类除草剂,它对于许多一年生和多年生杂草和双子叶植物都有极强的控制能力。
