Ethynyl Estradiol (below) is a synthetic hormone. The structure of ethynyl estradiol is similar to that of the naturally occurring estradiol. Like estradiol, ethynyl estradiol acts as an estrogen, but is more potent and lasts longer in the body. Ethynyl estradiol is commonly found in oral contraceptives for the prevention of ovulation and thinning the uterine lining. HO H H H HO 1. Predict the hybridization of each highlighted atom's atomic orbitals. 2. Label all polar bonds using the symbols \(\delta^+\) and \(\delta^-\). 3. How many \(\pi\) bonds can be found in the ethynyl estradiol structure? 4. Find a C-H bond containing a carbon atom having a hybrid orbital with 50% s-character.

0:00 Hello.

00:02 So the question given here is asking that which enzyme must be working in order for the body to produce estradiol, right? so we have to find the name of that enzyme, right? so what we know that all estrogens, these are synthesized from androgen precursors and the name of the enzyme is aromatis, right? what i'm saying, it's the aromatis.

00:34 So this enzyme converts the androgenic substrates and testosterone and we can say to the corresponding estrogens that is estrone and astrodial and estradiol.

00:51 So here they are asking the question for the astrodial.

00:54 So the name of the enzyme is aromatase, right? so here we got the name of the enzyme that is it's the aromatase.

01:04 Now here the second part of the question is asking us to find out that we have to select which of the following statements are true.

01:14 So the statement a, it's saying like progesterone is essential to pregnancy and promotes the growth of endometrium lining.

01:23 So what we know about the progestron that yes, this plays and a very important role in the development of fetters and what it stimulates the growth of the maternal breast tissue.

01:36 So here it stimulates the growth of the blood vessels also that supply the lining of the womb.

01:42 So that's why here this statement is true.

01:46 Moving to the next statement and it's saying about the estrogens that stimulates the development of lobes in the breast that create and release milk.

01:57 So yes, this is also true.

01:59 What we know, the hormone estrogen, this hormone is producing.

02:03 By the ovaries in the first half of the menstrual cycle and it stimulates the growth of milk ducts in the breast.

02:10 So here this answer is true.

02:13 Now moving to the statement c and it's saying like estrogen this is responsible for a fat distribution during puberty in the female.

02:24 So it is saying that estrogen is responsible for this...
