Ovarian hormones are usually

Options

A. Proteinaceous
B. Steroids
C. Amines
D. Modified amino acids.

Answer

To determine the chemical nature of ovarian hormones, we will analyze the options provided:

1. **Understanding Ovarian Hormones**: Ovarian hormones primarily include estrogen and progesterone, which are crucial for female reproductive functions.

2. **Analyzing the Options**:
- **Option 1: Proteinaceous**: These hormones are derived from proteins. An example is TSH (Thyroid Stimulating Hormone). Since ovarian hormones are not derived from proteins, this option is incorrect.
- **Option 2: Steroids**: Steroid hormones are derived from cholesterol and are lipid in nature. Estrogen and progesterone, the primary ovarian hormones, fall into this category. This option is likely correct.
- **Option 3: Amines**: Amines are derived from amino acids. Examples include epinephrine and norepinephrine. Since ovarian hormones do not fit this category, this option is incorrect.
- **Option 4: Modified Amino Acids**: These include hormones like catecholamines. Ovarian hormones do not belong to this group, making this option incorrect as well.

3. **Conclusion**: After evaluating all options, the correct answer is that ovarian hormones are usually **steroids**.

### Final Answer:
Ovarian hormones are usually **steroids**.
