The chemical formula of testosterone

Testosterone is a steroid hormone from the androgen group. It is the principal male sex hormone and the "original" anabolic steroid. Like other steroid hormones testosterone is derived from cholesterol. The largest amounts of testosterone are produced by testes, but it is also synthesized in smaller quantities by the theca cells of the ovaries, the zona reticulosa of the adrenal cortex, and the placenta.

Mayo Clinic Minute: All about testosterone

In the Chicago stockyards were happy to strike a deal with University of Chicago chemistry professor Fred Koch to take bovine testicles off their hands. There are accounts of some athletes in the ancient Greek Olympiads consuming sheep testicles to improve their performance. Professor Koch aimed at building on the work of his scientific predecessors, and although he had plenty of bovine testes to work with, he needed hands to do the tedious extraction.

Luckily, university professors are blessed with a natural resource available to them, namely, students. Koch recruited a number of them to mash the testicles, extract them with a solvent, and separate the components by column chromatography.

Eventually, from 40 pounds of testes the professor and his students managed to isolate 20 milligrams of a substance that when administered to castrated roosters, pigs and rats had the effect of re-masculinizing them. Serious research on the identification of this substance had to wait until more significant amounts became available.

That happened when pharmaceutical companies became interested in the therapeutic potential of such testicle extracts, with researchers at the Dutch company Organon finally managing to isolate a crystalline form of the hormone.

The exact structure of the molecule was worked out by Adolf Butenandt, then at the Schering pharmaceutical company. Once the structure was identified, Butenandt developed a chemical synthesis starting from cholesterol. A similar synthesis was carried out independently by Leopold Ruzicka at the Ciba company who went on to share the Nobel Prize for chemistry in with Butenandt.

While Butenandt made stellar contributions to chemistry, including the discovery of bombykol, the pheromone of the silkworm moth, his legacy is tainted by his involvement with the Nazi party. Ruzicka had numerous other accomplishments before the celebrated work on steroids. It was a powder with a long reputation of being an insecticide, made from crushed chrysanthemums that grew in Dalmatia, a region of Croatia.

Hundreds of years earlier, the Persians had discovered that chrysanthemums were toxic to insects, and since then, the powdered flowers, known as Pyrethrum, were used both to kill and repel insects.

Ruzicka determined that the oil contained several closely related compounds that came to be called pyrethrins, even managing to isolate and identify two of these. Pyrethrins have distinct fragrances and that led Ruzicka into perfume research, eventually determining the structure of muscone and civetone, scent compounds derived from the musk deer and the civet cat. The discovery of testosterone led to its therapeutic use both for breast cancer and for the treatment of men with low levels of the hormone.

Because testosterone also builds muscle, it has been used and abused by athletes. German athletes in the Olympics used testosterone for performance enhancement, but it was state-sponsored doping by East Germany under Soviet rule that eventually put testosterone and its synthetic derivatives on the world stage.

Vector - The chemical molecular formula of the hormone testosterone. Male sex hormone.

The effect of testosterone propionate and growth hormone on the growth of muscle, bone, pelt, viscera and seminal vesicles was studied in hypophysectomized male rats. Testosterone 0. Growth hormone 0. Testosterone did not enhance the growth-promoting effect of growth hormone in any tissue except the levator ani muscle.

Testosterone is the primary male sex hormone and anabolic steroid. Testosterone is a steroid from the androstane class containing a keto and hydroxyl groups at positions three and seventeen respectively.

Back to Compounds. Testosterone belongs to the class of organic compounds known as androgens and derivatives. These are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans.

Introduction What are "bioidentical hormones?

Testosterone is a male sex hormone that is important for sexual and reproductive development. The National Institutes of Health regards testosterone as the most important male hormone. Women also produce testosterone, but at lower levels than men. Testosterone belongs to a class of male hormones called androgens, which are sometimes called steroids or anabolic steroids. In men, testosterone is produced mainly in the testes, with a small amount made in the adrenal glands. The brain's hypothalamus and pituitary gland control testosterone production.

What is Testosterone?

Поторопись, - крикнул ей вдогонку Стратмор, - и ты еще успеешь к ночи попасть в Смоки-Маунтинс. От неожиданности Сьюзан застыла на месте.

Она была уверена, что никогда не говорила с шефом о поездке. Она повернулась. Неужели АНБ прослушивает мои телефонные разговоры. Стратмор виновато улыбнулся.

Молодой лейтенант пустил туда Беккера по распоряжению севильской гвардии - похоже, у этого приезжего американца имелись влиятельные друзья. Беккер осмотрел одежду. Среди вещей были паспорт, бумажник и очки, засунутые кем-то в один из ботинков. Еще здесь был вещевой мешок, который полиция взяла в отеле, где остановился этот человек.

- Я шпионил за Стратмором. Эти письма в моем компьютере скопированы с терминала Стратмора - это сообщения, которые КОМИНТ выкрал у Танкадо. - Чепуха. Ты никогда не смог бы проникнуть в почту коммандера.

Это вам не Америка - никаких предупреждающих знаков, никаких поручней, никаких табличек с надписями, что страховые компании претензий не принимают. Это Испания. Если вы по глупости упадете, то это будет ваша личная глупость, кто бы ни придумал эти ступени.

Какие же страшные были у него руки. - Вот тут-то вы и рассмотрели его кольцо.

И я уверена, что большинство наших граждан готовы поступиться некоторыми правами, но знать, что негодяи не разгуливают на свободе. Хейл промолчал. - Рано или поздно, - продолжала она, - народ должен вверить кому-то свою судьбу.

В нашей стране происходит много хорошего, но немало и плохого.

Когда он наконец заговорил, голос его звучал подчеркнуто ровно, хотя было очевидно, что это давалось ему нелегко. - Увы, - тихо сказал Стратмор, - оказалось, что директор в Южной Америке на встрече с президентом Колумбии.

Поскольку, находясь там, он ничего не смог бы предпринять, у меня оставалось два варианта: попросить его прервать визит и вернуться в Вашингтон или попытаться разрешить эту ситуацию самому. Воцарилась тишина. Наконец Стратмор поднял усталые глаза на Сьюзан. Выражение его лица тут же смягчилось. - Сьюзан, извини .

Беккер знал лишь, что немец был с рыжеволосой спутницей, а в Испании это само по себе большая редкость. Клушар вспомнил, что ее звали Капля Росы.

Беккер скорчил гримасу: что это за имя.

    It agree, this rather good idea is necessary just by the way
