Definition

1. Noun:
   • The removal of iodine atoms from organic compounds: A chemical process where iodine atoms are detached or eliminated from molecules, often altering their biological activity or chemical properties.

Usage

• Noun:
  • De-iodination is a key metabolic step in the regulation of thyroid hormones.
  • The enzyme is responsible for the de-iodination of the compound, rendering it inactive.

Advanced Usage

• "Catalytic de-iodination": Refers to de-iodination facilitated by a catalyst.
  • The study focused on the catalytic de-iodination of environmental pollutants.
• "Enzymatic de-iodination": Specifically describes de-iodination carried out by an enzyme.
