代谢
levomefolic 酸通过维生素 B12 依赖性酶甲硫氨酸合成酶转化为四氢叶酸 (THF),然后通过叶酸多聚谷氨酸合成酶 (FPG) 进行有效的多聚谷氨酰化。叶酸的多聚谷氨酸形式对于叶酸依赖性反应中的相关酶来说更有效的底物。
Levomefolic acid is further converted into tetrahydrofolate (THF) via the vitamin B12-dependent enzyme methionine synthase before effective polyglutamylation by folylpolyglutamate synthetase (FPG). Polyglumate forms of folic acids are more effective substrates for associated enzymes in folate-dependent reactions.
