Which of the following is an amino acid derived hormone ?

Options

A. Estradiol
B. Ecdysone
C. Epinephrine
D. Estriol

Explanation

To determine which of the following is an amino acid-derived hormone, we will analyze the options provided and identify the correct answer based on the characteristics of amino acid-derived hormones.

### Step-by-Step Solution:

1. **Understanding Hormones**:
- Hormones are chemical messengers produced in one part of the body and transported via the bloodstream to target organs, where they induce physiological changes.

2. **Classification of Hormones**:
- Hormones can be classified based on their chemical structure. One such classification is amino acid-derived hormones, which are derived from amino acids, the building blocks of proteins.

3. **Analyzing the Options**:
- **Option A: Estradiol and Estriol**:
- These are ovarian hormones and belong to the category of steroid hormones, not amino acid-derived hormones.
- **Option B: Ecdysone**:
- This hormone is related to molting in insects and is not relevant to human physiology. It is also not an amino acid-derived hormone.
- **Option C: Epinephrine (Adrenaline)**:
- Epinephrine is secreted by the adrenal glands and is known as the "fight or flight" hormone. It is derived from the amino acid tyrosine, making it an amino acid-derived hormone.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option C: Epinephrine**.

### Final Answer:
The amino acid-derived hormone from the given options is **Epinephrine (Adrenaline)**.
