Chemically epinephrine is

Options

A. Amino acid derivative
B. Steroid
C. Peptide
D. Glucocorticoid

Answer

To determine the chemical classification of epinephrine, we can follow these steps:

1. **Identify the Nature of Epinephrine**: Epinephrine is a hormone that is involved in the body’s response to stress. It is commonly known as adrenaline.

2. **Understand the Chemical Composition**: Epinephrine is derived from the amino acid tyrosine. This means that its structure is based on amino acids, which are the building blocks of proteins.

3. **Categorize Epinephrine**: Since epinephrine is derived from an amino acid, it is classified as an amino acid derivative. This distinguishes it from other types of hormones such as steroids, peptides, or glucocorticoids.

4. **Conclusion**: Based on the information gathered, we can conclude that chemically, epinephrine is an amino acid derivative.

5. **Final Answer**: The correct answer to the question "Chemically epinephrine is" is: **Amino acid derivative**.
