Тестостерон является естественным мужским половым гормоном в организме человека. It produce mainly in the testicles of men and in small amounts in the ovaries and adrenal glands of women. Testosterone is a steroid compound with a typical sterane core structure consisting of three carbon five-membered rings and one carbon four-membered ring. It has the formula C19H28O2 and belongs to the androstane family, specifically the 17-β-hydroxy-androstane-3-1 family.
The main chemical characteristics of testosterone
- Two hydroxyl groups in the C-19 position. Through these two hydroxyl groups, testosterone can bind to testosterone receptors and exert biological activity.
- A hydroxyl group at the C-17 position. By migrating the hydroxyl group, it generate the effect of estrogen.
- Seven carbon-carbon double bonds. These carbon-carbon double bonds give the molecule a planar structure that facilitates binding to testosterone receptors.
The structure of testosterone determines its biological function
- After binding to testosterone receptors, it activates related signal transduction pathways, promotes muscle protein synthesis, increases muscle size and strength, helps maintain bone density and prevent osteoporosis. В то же время, it regulates secondary sexual characteristics, such as stimulating sperm production, affecting sexual desire and sexual function.
- The hydroxyl group of C-17 is easily reduced to a keto group, producing dihydrotestosterone (Dht), which has a higher affinity and can more effectively promote the development of secondary sexual characteristics and maintain sexual function.
- Testosterone can be converted into estrogen through the displacement reaction and the removal of hydroxyl groups, which has the role of regulating secondary sex characteristics and promoting bone health.
- Testosterone has a typical sterol structure, which is conducive to its passage through biofilms. And can bind SHBG and other binding proteins, convenient transport in the blood, play a role in various parts of the body.
- Variations in the structure of testosterone can produce different derivatives or analogues with different biological effects and pharmacokinetic properties, playing a huge medical role.
В итоге, the chemical structure of тестостерон определяет его множественные биологические эффекты. Из химического строения, Мы можем знать, какую роль он может играть. Благодаря изучению его химической структуры, Биологи могут найти и синтезировать различные производные тестостерона, которые играют разные роли в разных областях и обеспечивают новые методы лечения здоровья и болезней.
