스테로이드 란 무엇입니까??
스테로이드는 분자 구조를 가진 천연 또는 합성 유기 화합물입니다. 17 4개의 고리로 배열된 탄소 원자. They include sex hormones, adrenal cortical hormones, bile acids, and sterols.
스테로이드, any of a class of natural or synthetic organic compounds characterized by a molecular structure of 17 4개의 고리로 배열된 탄소 원자. Steroids are important in biology, chemistry, and medicine.

1. Steroid hormones are endogenous substances found in the study of mammalian endocrine systems.

2, between 1932 그리고 1939, obtained pure crystal of Estrone (1932), Estradiol (1932), 남성 호르몬 (1935) and Corticosterone (1939) from the gland, Then the chemical structure of steroid was elucidated, and a new field of steroid chemistry and steroid drug chemistry was created. Many significant achievements followed.

3. Invented the semi-synthetic production of steroid drugs with Diosgenin as raw material, which expanded the production scale and reduced the cost.

4, the discovery of adrenocortical hormone in the treatment of rheumatoid arthritis and its important value in immune regulation, so that steroid drugs become indispensable drugs in the hospital.

5. The success of the study of steroid oral contraceptives has brought human birth control to a new level.

The steroid group includes all the sex hormones, adrenal cortical hormones, bile acids, and sterols of vertebrates, as well as the molting hormones of insects and many other physiologically active substances of animals and plants. Among the synthetic steroids of therapeutic value are a large number of anti-inflammatory agents, anabolic (growth-stimulating) agents, and oral contraceptives.
Different categories of steroids are frequently distinguished from each other by names that relate to their biological source—e.g., phytosterols (found in plants), adrenal steroids, and bile acids—or to some important physiological function—e.g., progesterones (promoting gestation), androgens (favouring development of masculine characteristics), and cardiotonic steroids (facilitating proper heart function).
Steroids vary from one another in the nature of attached groups, the position of the groups, and the configuration of the steroid nucleus (or gonane). Small modifications in the molecular structures of steroids can produce remarkable differences in their biological activities.

This article covers the history, chemistry, biological significance, and basic pharmacology of steroids. For more information about the physiological relevance and the pharmacological applications of steroids, see human endocrine system, endocrine system, and drug.
