Question

Which of the following hormones is a derivation of fatty acid?

• A. Gastrin
• B. Thyroxin
• C. Estrogen
• D. Prostaglandins

Answer 1

The correct option is D Prostaglandins

Thyroxin is iodinated amino acid hormone. Estrogen has three cyclohexyl rings and one cyclopentyl ring and is a steriod hormone. Gastrin is a peptide hormone. Prostaglandins are the derivatives of arachidonate, a fatty acid that stimulates the blood clotting process. These are also involved in the reproductive process like the delivery of the foetus.

Thus, the correct answer is option D.
