Стероиды: классификация

Три наиболее важные группы стероидов составляют стерины, желчные кислоты и стероидные гормоны. Кроме того, к стероидам относят соединения растительного происхождения, обладающие ценными фармакологическими ...

 
А. Стерины

Стеринами называются стероидные спирты. Все стерины содержат (β-гидроксильную группу при С-3 и одну или несколько двойных связей в кольце В и боковой цепи. В молекулах стеринов отсутствуют карбоксильные ...

А. Стерины
Б. Желчные кислоты

Из холестерина в печени образуются желчные кислоты (см. Желчные кислоты). По химическому строению эти соединения близки к холестерину. Для желчных кислот характерно наличие укороченной разветвлённой боковой цепи ...

Б. Желчные кислоты
В. Стероидные гормоны

Биосинтез стероидных гормонов — процесс не столь заметный в количественном отношении — имеет вместе с тем большое физиологическое значение (см. Метаболизм стероидных гормонов). Стероиды образуют группу липофильных сигнальных веществ, ...

В. Стероидные гормоны
