Question

although both the female sex hormones estradiol and progesterone have the same precursor cholesterol, they differ in structure. identify the structural differences. select all that apply.

select all that apply:

a hydroxyl group in estradiol is replaced by a double bond to oxygen in progesterone.

progesterone has an extra methyl group.

a hydroxyl group in estradiol is replaced by a carboxyl group in progesterone.

a hydroxyl group in estradiol is replaced by an acetyl group (-co-ch) in progesterone

Explanation:

• Estradiol has hydroxyl groups (\(-OH\)), while progesterone has carbonyl groups (\(C = O\)).
• By comparing the structures, we can see that progesterone has an extra methyl group (\(-CH_3\)).

Answer:

A. A hydroxyl group in estradiol is replaced by a double bond to oxygen in progesterone.
B. Progesterone has an extra methyl group.
