How many moles of ethynyl estradiol are there in one pill How many molecules is this How many carbon atoms are in a 0.035-mg sample of ethynyl estradiol What mass of carbon is this ... 

The fight against aging should take into account not only the damage caused by the various sources of cell oxidation but also the fall in hormone levels. For menopausal or postmenopausal women, a standard formula is testosterone propionate 100 mg, estrone 5 mg, estradiol benzoate 5 mg, and water in oil excipient ad 100 g. 

Estradiol transdermal system is designed to deliver 17(beta)-estradiol continuously and consistently over a 3-or 4-day interval on application to intact skin. Three strengths of Alora systems are available, having nominal in vivo delivery of 0.05, 0.075, and 0.1 mg estradiol per day through skin of average permeability (interindividual variation in skin permeability is approximately 20%). Alora systems have contact surface areas of 18, 27, and 36 cm2 and contain 1.5, 2.3, and 3.0 mg of estradiol USP, respectively. The composition of the systems per unit active surface area is identical. Estradiol USP [17(beta>-estradiol] is a white, crystalline powder that is chemically described as estra-l,3,5(10)-triene-3,17(beta)-diol, has an empirical formula of and has a molecular...

Estradiol is made by the cells of a follicle in the ovary containing an ovum that is ready to be expelled. In the male the interstitial cells produce testosterone, one of the male sex hormones. It is converted into (indrosterone. Their formulas are... 

Estradiol is a female sexual hormone that causes maturation and maintenance of the female reproductive system. Elemental analysis of estradiol gave tire mass percent composition C, 79.37% H, 8.88% 0,11.75%. The molar mass of estradiol is 272.37 g/mol. Find the molecular formula of estradiol. 

In the animal organism, cholesterol is the starting point for the synthesis of other steroids, such as sex hormones and bile acids. In fact, GC-MS analyses and radio immunoassays show that among the sex hormones, progesterone (I in Formula 3.102) appears most often in animal food. It is enriched in the fat phase, leading to relatively high concentrations in butter (Table 3.50). Traces of this steroid also occur in plant foods. Testosterone (II in Formula 3.102), 3,17-estradiol (III) and 17-estrone (IV) are other sex hormones which have been identified as...

Perhaps the most interesting questions, however, in this problem arise in relationship to the sex hormones. This is not the place to give a complete summary of the development of our knowledge of this subject. By the early 1930s the constitution of the naturally occurring estrogens had been deduced and they are five in number estriol, estrone, estradiol equilene, and equilenin. The formulae are reproduced below (b, c, d, e, f).
