Sentences with phrase «hormone deiodinases»

Selenium makes up a component of enzymes, called thyroid hormone deiodinases, which help activate and inactivate thyroid hormones, which regulates your thyroid function.

Not exact matches

It's a five — the enzyme that converts T4 to T3 inactive thyroid hormone to active thyroid hormone is a 5 deiodinase enzyme.

Because it is the activity of these deiodinases and transport of T4 and T3 into the cell that determines tissue and cellular thyroid levels and not serum thyroid levels, serum thyroid hormone levels may not necessarily predict tissue thyroid levels under a variety of physiologic conditions.

To accurately assess thyroid function, it must be understood that deiodinase enzymes are essential control points of cellular thyroid activity that determine intracellular activation and deactivation of thyroid hormones.

The T3 hormone is known as the «metabolically active» hormone and is produced by the conversion of the «metabolically inactive» T4 hormone (by the deiodinase system).

Interrelationships among thyroxine, growth hormone, and the sympathetic nervous system in the regulation of 5 - iodothyronine deiodinase in rat brown adipose tissue.

Thyroid hormone metabolism is impaired without selenium because iodine - based enzymes, called iodothyronine deiodinases, can not be synthesized.

Although very minor amounts of selenium appear sufficient for adequate activity of deiodinases, thus limiting the impact of its potential deficiency on synthesis of thyroid hormones, selenium status appears to have an impact on the development of thyroid pathologies.

Selenium - containing deiodinase enzymes are required to convert inactive thyroid hormone to its active form.

«A wide variety of organochlorine compounds and pesticides have an effect on the thyroid hormones in plasma, tissues and deiodinase enzymes, which are in charge of stabilising the thyroid hormones in tissues.»
