Steroids
Steroids (Greek adjective στερ [ιν] οειδή from στερεÏŒ, stereo: "the solid, rigid, solid" (based on molecular properties) and the suffix-ÖID are "similar") a chemical class of lipids (molecules with lipophilic groups in the generally insoluble in water). Steroids are derivatives of the hydrocarbon Sterane) (Cyclopentanoperhydrophenanthren.
Natural steroids are found in animals, plants and fungi. Their biochemical functions, ranging from vitamins and sex hormones (androgens in males or estrogens in women) on bile acid and toxic toads to the herzaktiven poisons of digitalis and oleander.
In animals and in humans cholesterol is the principal steroid; plants containing it are not. Cholesterol lipoproteins and steroid hormones are developed, such as the hormones of the adrenal cortex) (corticosteroids. Artificial derivatives of the male
Sex hormone testosterone, anabolic steroids are used as muscle preparations. These are also known as doping in sports to an interested public is aware.
Steroids Structure
All steroids are based on cholesterol (with the exception of Retinoic acids), which is composed of the triterpene squalene. This framework must be Sterane. A structural commonality is the
Cyclopentanoperhydrophenanthren-ring (except vitamin D). Steroids have (a rigid molecular shape hence the name), usually a relatively high melting point and are easy to crystallize. Due to the asymmetric carbon atoms at the
Ring links are numerous structural isomers are possible, which are folded differently.
Steroids reduce
In humans, the water-soluble steroids are made in the liver by hydroxylation and conjugation with glycine or taurine and as bile acids in bile into the duodenum (the front part of the small intestine excreted).
Steroid hormone
Steroid hormones are steroids which act as hormones. They include the sex hormones of the gonads and the adrenal corticosteroids. The steroid hormones of mammals can be divided into five groups, according to the steroid receptors to which they bind: glucocorticoids, mineralocorticoids, androgens, estrogens and progestins.
What are steroids?
Anabolic steroids (anabolic steroids) are artificially produced hormones that are transforming chemically with the male sex hormone testosterone Effect of anabolic steroids
We distinguish between the desired (anabolic) and undesirable (androgenic) effect of anabolic steroids
Anabolic steroids Effects:
The anabolic steroids (anabolic steroids) affect the metabolism, especially on protein metabolism. This anabolic effect is sought by the users of anabolic steroids, as they build the protein in muscle, promotes and reduces body fat. Anabolic steroids (anabolic steroids) work only with simultaneous intensive training.
Anabolic Steroids
Anabolic steroids are synthetic derivatives of the male sex hormone testosterone. They were in the 2nd World War II and were originally developed to allow weakened and malnourished prisoners of war to a better recovery.
They were also used because of its protein anabolic effect on consumptive diseases and muscular as well as a remedy for anemia. Very soon they also found application in sports where they were administered as illicit drugs to improve performance in healthy athletes.
Anabolic steroids in medicine today come with a failure of the testes (lack of education), the body's testosterone, for growth or physical weakness (eg the elderly) are used. In general, they belong to the group of anabolic steroids.
Effect of steroids
All the usual preparations are based on the male sex hormone testosterone. These two effects are distinguished:
The effect of anabolic steroids on protein metabolism, which is desired by the users, the structure of the protein increased in the muscle while reducing body fat. An effect is only obtained with simultaneous intensive weight training. In addition, anabolic steroids can enhance regenerative capacity of the consumer. He can thus exercise more frequently and with fewer pauses
