Which of the following is an incorrect match?

Options

A. Thyroxine - Iodinated tyrosine
B. Aldosterone - Polypeptide hormone
C. Estrogen - Steroid hormone
D. Thyrotropin - Glycoprotein hormone

Answer

To determine which of the following is an incorrect match, let's analyze each option provided:

1. **Thyroxine and iodinated tyrosine**:
- Thyroxine is a hormone produced by the thyroid gland. It is derived from the amino acid tyrosine and contains iodine atoms. Therefore, this match is correct.

2. **Aldosterone and polypeptide hormone**:
- Aldosterone is a hormone produced by the adrenal glands. It is classified as a steroid hormone, not a polypeptide hormone. Therefore, this match is incorrect.

3. **Estrogen and steroid hormone**:
- Estrogen is a hormone produced primarily by the ovaries and is classified as a steroid hormone. Therefore, this match is correct.

4. **Thyrotropin (TSH) and glycoprotein hormone**:
- Thyrotropin, also known as Thyroid Stimulating Hormone (TSH), is produced by the pituitary gland and is classified as a glycoprotein hormone. Therefore, this match is correct.

Based on the analysis, the incorrect match is:

**Aldosterone and polypeptide hormone.**

### Summary of the Solution:
- **Correct Matches**:
- Thyroxine - iodinated tyrosine
- Estrogen - steroid hormone
- Thyrotropin - glycoprotein hormone
- **Incorrect Match**:
- Aldosterone - polypeptide hormone

### Final Answer:
The incorrect match is **Aldosterone and polypeptide hormone**.
