Question

Which hormone does not contain polypeptide?

• A. Oxytocin
• B. Prostaglandins
• C. Insulin
• D. ADH

Answer 1

The correct option is B Prostaglandins

Prostaglandins are lipid compounds synthesised from fatty acids. They have hormone like effects. They act inside the cells by modifying cellular responses.

Oxytocin, Insulin and ADH (Antidiuretic hormone) are peptide hormones. Oxytocin and ADH are secreted from posterior lobe of pituitary gland and insulin is secreted from beta cells of islets of Langerhans of pancreas.

So, the correct answer is 'Prostaglandins'.
