Number of amino acids present in hormone adrenocorticotrophin is

Options

A. 10
B. 70
C. 58
D. 39

Answer

To determine the number of amino acids present in the hormone adrenocorticotropic hormone (ACTH), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Hormone**: The hormone in question is adrenocorticotropic hormone, commonly abbreviated as ACTH.

2. **Understand the Source**: ACTH is secreted by the anterior pituitary gland, which is known as one of the master glands in the endocrine system.

3. **Recognize the Function**: ACTH acts as a tropic hormone, meaning it stimulates another endocrine gland, specifically the adrenal cortex, to release hormones such as glucocorticoids (e.g., cortisol).

4. **Determine the Structure**: The structure of ACTH is composed of a specific number of amino acids.

5. **Find the Number of Amino Acids**: Research or reliable sources indicate that ACTH is made up of 39 amino acids.

6. **Select the Correct Option**: Given the options (10, 70, 58, 39), the correct answer is 39.

### Final Answer:
The number of amino acids present in the hormone adrenocorticotropic hormone (ACTH) is **39**.
