de-iodinase
Definition
- Noun:
- An enzyme that removes the iodine radical: De-iodinase is a specific type of enzyme responsible for catalyzing the removal of iodine atoms from molecules, particularly from thyroid hormones.
Usage
- Noun:
- De-iodinase activity is crucial for regulating thyroid hormone levels in the body.
- Researchers are studying the function of de-iodinase in metabolic processes.
Examples
- Noun:
- The de-iodinase enzyme converts the hormone T4 into the more active T3.
- A deficiency in de-iodinase can lead to hormonal imbalances.
Advanced Usage
"De-iodinase pathway": Refers to the biochemical route involving de-iodinase enzymes.
- The de-iodinase pathway is a key mechanism for local thyroid hormone activation in tissues.
"De-iodinase inhibition": The act of blocking or reducing the activity of this enzyme.
- Certain environmental toxins can cause de-iodinase inhibition.
