General description

Ethylenediaminetetraacetic acid (EDTA) is a substituted diamine and a chelator of metal ions. It has anticoagulant and antibacterial activity. EDTA is an inhibitor of metalloprotease. It evades the undesirable effects of ferric, cupric and manganic ions in bleaching. It blocks cellular division, chlorophyll synthesis and algal biomass production.

Application

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