Description

General description

Ethylenediaminetetraacetic acid disodium salt dihydrate, referred to as EDTA is a widely used chelator of divalent cations like Ca⁺². It can inhibit proteases dependent on metal ions, such as, calcium-dependent cysteine proteases. EDTA also acts as a chelator of the Zn ion, inhibiting metalloproteases that require zinc for activity.

Application

Ethylenediaminetetraacetic acid disodium salt dihydrate has been used along with Na₂HPO4 and citric acid for preparing Na₂EDTA-McIlvaine buffer. Aqueous solution of Ethylenediaminetetraacetic acid disodium salt dihydrate has also been used for photocatalytic hydrogen production

Chelator of divalent cations. Inhibits enzymes, such as metalloproteases, that require divalent cations for activity.
