金属硫蛋白(Metallothioneins,简称MTs)是一类由金属离子诱导产生的具有丰富巯基的低分子蛋白。哺乳动物每克分子MT大约可与7克离子金属结合,形成金属螯合物。因此,MT被认为可作重金属解毒剂。据报道,Cd-硫蛋白(Cd-MT)的解离常数是10~(-25),而Zn-硫蛋白(Zn-MT)是10~(-21),故Zn-MT对Cd中毒有保护航效应。本研究观察了MT[剂量为国防科工委性天医学工程研究所潘爱华所报道(内部资料)小 Metallothioneins (MTs) are a class of low-molecular-weight sulfhydryl-rich proteins induced by metal ions. Mammals can bind approximately 7 grams of ionic metal per mole of MT forming a metal chelate. Therefore, MT is considered as a heavy metal antidote. It has been reported that the dissociation constant of Cd-thione protein (Cd-MT) is 10 to (-25), while that of Zn-thionein is 10 to (-21) Protect aviation effect. This study observed the MT [dose for the National Defense Science and Technology Institute of Sexual Medicine Pan Aihua reported (internal data) small
