Question
In terms of its chemical nature, antidiuretic hormone is classified as ______.
- peptide
- amino acid derivative
- steroid
- glycolipid
Solution
Antidiuretic hormone (ADH), also known as vasopressin, is classified as a peptide. Peptide hormones are made up of chains of amino acids and play various roles in the body, including the regulation of water balance. ADH specifically acts on the kidneys to promote water reabsorption, thereby concentrating the urine and reducing urine volume.
Explanation of Options:
- Peptide: Correct. ADH is synthesized in the hypothalamus and stored in the posterior pituitary gland, composed of amino acids.
- Amino Acid Derivative: Incorrect. While ADH is derived from amino acids, the term usually refers to hormones like thyroxine.
- Steroid: Incorrect. Steroid hormones are derived from cholesterol and have different functions and mechanisms.
- Glycolipid: Incorrect. Glycolipids are a class of lipids that are important in cell membrane structure, not hormones.
Final Answer:
Antidiuretic hormone is classified as peptide.
