Question

progesterone and testosterone are both synthesized from cholesterol. how do they differ? select all that apply.
select all that apply:
testosterone is a male sex hormone, and progesterone is a female sex hormone.
the only structural difference between the two hormones is at c - 17 of the d - ring. c - 17 of progesterone is a carbonyl carbon, and testosterone has a hydroxyl group on c - 17.
the only structural difference between the two hormones is at c - 17 of the d - ring. progesterone has an acetyl group at that c - 17, and testosterone has a hydroxyl group.
there are structural differences at c - 3 of the a - ring and c - 17 of the d - ring.

Explanation:

• Testosterone is a male sex hormone, while progesterone is a female sex hormone.
• Progesterone has an acetyl group at C - 17 of the D - ring, and testosterone has a hydroxyl group at C - 17.
• There are no structural differences at C - 3 of the A - ring.

Answer:

• Testosterone is a male sex hormone, and progesterone is a female sex hormone.
• The only structural difference between the two hormones is at C - 17 of the D - ring. Progesterone has an acetyl group at that C - 17, and testosterone has a hydroxyl group.
