一般描述

乙二胺四乙酸(EDTA)是一种氨基聚羧酸和六齿配体。可与金属离子,特别是与阳离子螯合,形成八面体络合物。乙二胺四乙酸二钠盐(EDTA)是一种血液抗凝剂,与假性血小板减少症的致病原因有关。它与血液中的钙螯合,抑制凝血,常规用于血液学检查。增强溶菌酶的抗菌活性。螯合疗法中使用EDTA与钙螯合,有利于动脉粥样硬化血管疾病中动脉的扩张和动脉粥样硬化斑块的溶解。EDTA螯合疗法还可以在肝纤维化过程中,保护血液和脂质过氧化免受氧化损伤。

应用

乙二胺四乙酸二钠盐二水合物用于植物物种的种子萌发试验以及从苔藓Physcomitrella paten中提取蛋白质。 还用于裂解和液泡缓冲液,用于从矮牵牛花瓣中分离液泡。
二价阳离子的螯合剂。抑制需要二价阳离子才能具有活性的酶,例如金属蛋白酶。
