Complex fatty acids that function as intercellular messengers are

Options

A. Prostaglandins
B. Catecholamines
C. Sphingolipids
D. Steroids.

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for complex fatty acids that function as intercellular messengers.

2. **Understand the Context**: Intercellular messengers are substances that facilitate communication between cells. In biological systems, these can include hormones and other signaling molecules.

3. **Recall Relevant Information**: Prostaglandins are known to be lipid compounds that act similarly to hormones and are involved in various physiological functions.

4. **Define Prostaglandins**: Prostaglandins are a group of physiologically active lipid compounds derived from arachidonic acid, a 20-carbon unsaturated fatty acid. They belong to a larger class of compounds known as eicosanoids.

5. **Discuss Their Function**: Prostaglandins have diverse hormone-like effects and are found in almost every tissue in humans and other animals. They play crucial roles in processes such as inflammation, blood flow, and the formation of blood clots.

6. **Conclusion**: Based on the information, the correct answer to the question is prostaglandins, as they are complex fatty acids that function as intercellular messengers.

7. **Final Answer**: The complex fatty acids that function as intercellular messengers are **prostaglandins**.
