Question:
CRH is an example of –
CRH is an example of –
Show Hint
Almost all hypothalamic releasing and inhibiting hormones (such as CRH, TRH, GnRH, and GHRH) are peptide hormones.
Updated On: Jul 6, 2026
- Steroid hormone
- Amino acid derivative
- Peptide hormone
- Cytokine
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Hormones are chemically classified into peptides/proteins, steroids (lipid-derived), or amino acid derivatives (tyrosine/tryptophan-derived).
Step 2: Detailed Explanation:
1. CRH stands for Corticotropin-Releasing Hormone.
2. It is synthesized by neurosecretory neurons in the paraventricular nucleus of the hypothalamus.
3. Biochemically, CRH is a single-chain peptide hormone consisting of 41 amino acids.
4. It travels via the hypophyseal portal system to stimulate the release of ACTH from the anterior pituitary gland.
Therefore, CRH is classified as a peptide hormone.
Step 3: Final Answer:
The correct option is 3, which corresponds to Peptide hormone.
