Definition
  1. Noun:
    • A synthetic chemical compound: Ethylenediaminetetraacetic acid is a man-made, complex organic molecule.
    • A chelating agent: Its primary function is to bind tightly to specific metal ions, forming stable, soluble complexes that can be removed from the body or a system.
Usage
  • Ethylenediaminetetraacetic acid is used as a treatment for acute lead poisoning.
  • In laboratory research, ethylenediaminetetraacetic acid is added to samples to prevent metal ions from interfering with reactions.
  • The stability constant of the complex formed by ethylenediaminetetraacetic acid and calcium is very high.
Advanced Usage
  • "EDTA therapy": A medical treatment involving the administration of ethylenediaminetetraacetic acid or its salts to remove toxic metals.
    • The patient underwent EDTA therapy for heavy metal detoxification.
  • "EDTA anticoagulant": The use of ethylenediaminetetraacetic acid salts in blood collection tubes to prevent clotting by binding calcium ions.
    • Blood samples for complete blood counts are typically drawn into tubes containing EDTA anticoagulant.
Variants and Related Words
  • EDTA (n): The universal abbreviation for ethylenediaminetetraacetic acid.
    • EDTA is a common additive in many processed foods and cosmetics.
  • Chelator (n): A general term for any agent, like ethylenediaminetetraacetic acid, that binds metal ions.
    • The doctor prescribed a chelator to treat the iron overload.
Synonyms
  • Chelating agent: A substance that forms multiple bonds with a single metal ion.
  • Sequestering agent: A substance that removes metal ions from solution.
Related Phrases
  • "EDTA disodium salt": A common salt form of ethylenediaminetetraacetic acid used in medicine and industry.
    • The solution was buffered with EDTA disodium salt.
  • "Metal-EDTA complex": The compound formed when ethylenediaminetetraacetic acid binds to a metal ion.
    • The formation of the lead-EDTA complex renders the metal nontoxic and excretable.
