Question

Test Your Understandin Create an outline or flow chart secretes each hormone. 8. the categories and subcategories of the steroid hormones. Indicate the gland of 9. What are "anabolic steroids," and why do some athletes and bodybuilders illegally (and ill-advisedly) ta Describe some of their side effects, and explain the mechanisms of how they can (a) stimulate growth of female-like breast tissue in men and (b) cause atrophy of the testes. 10. Which of the steroid hormones used in this exercise was most soluble in the solvent? Which was least soluble? Explain.

Explanation / Answer

8) steriod harmones: cholesterol is precursor for 5 steriod harmone classes they are 1) progestagens, 2)glucocorticoids 3)mineralocorticoids 4) androgens, 5) estrogens , the glcocorticoids and mineralocorcoids are synthesis in adernal cortex and estogen (in ovary)and progestagens( in corpus luteum) in female, and testosteone(in testis) in males, the cholesterol converted tp pregnenolone( precursor of all steriods) it is converted into progesterone converted into 17 - a- hydroxyprogesterone and it is converted into androstenedione ( sex harmone precursor of estrone, testosterone , estradiol), 17-a-hydroxyprogesterone converted into 11 deoxycortisol and it is convered into cortisol, androstenedione converted to estrone or androstenedione converted to testosterone, and progesterone converted to 11 deoxycorticosterone and this is converted to corticosterone and it is converted to aldosterone. 9) Anabolic steriods are also known as anabolic -androgenic steriods, these include natural androgens like testosterone as well as synthetic androgens , these steriods lead to increased protein synthesis in cells that causes increase in the muscle mass in individuals, and can increase energy and libido and can increase muscle mass and decreased body fat ( without even excercise) can alleviates depression and it make one sterile ,acne and shrinkage of genitalia , these steriods in high amount cause some to be converted to estrogen, excess estrogen causes breast tissue development, high levels cause the body to stop producing its own testosterone so then they shutdown they also decreases in the genitiale size. 10) The steriod harmones are most soluble in solvent are beta estradiol because it travels the furthest up the plate in comprasion to the rest of the spots, the steriod harmone which are least soluble within the solvent are hydrocortisone because it travelled the least distances up the plate.
