ЧТО ОЗНАЧАЕТ СЛОВО THYROXINE
Гормон щитовидной железы
Гормоны щитовидной железы, трийодтиронин и его прогормоны, тироксин, являются тирозиновыми гормонами, продуцируемыми щитовидной железой, которые в первую очередь ответственны за регуляцию метаболизма. Йод необходим для получения Т3 и Т4. Дефицит йода приводит к снижению продуцирования Т3 и Т4, увеличивает ткань щитовидной железы и вызывает заболевание, известное как зоб. Основной формой гормонов щитовидной железы в крови является тироксин, который имеет более длительный период полувыведения, чем Т3. Отношение T4 к T3, высвобождаемое в кровь, составляет примерно от 20 до 1. Т4 превращается в активный Т3 в клетках с помощью дейодиназ. Они дополнительно обрабатываются декарбоксилированием и деиодинированием для получения йодтиронинамина и тиронинамина. Все три изоформы деиодиназ являются ферментами, содержащими селен, поэтому диетический селен необходим для производства Т3.
Значение слова thyroxine в словаре английский языка
Определение тироксина в словаре является основным гормоном, продуцируемым щитовидной железой: оно увеличивает метаболический уровень тканей, а также контролирует рост, как в метаморфозе амфибий. Он может быть синтезирован или извлечен из щитовидной железы животных и используется для лечения гипотиреоза. Химическое название: тетра-йодтиронин; формула: C15H11I4NO4.
