Acetyl CoA is a precursor of _______ synthesis

Options

A. protein
B. fatty acids
C. organic acids
D. carbohydrates

Answer

**Step-by-Step Solution:**

1. **Understanding Acetyl-CoA**: Acetyl-CoA is a crucial molecule in metabolism, acting as a central intermediate in various biochemical pathways.

2. **Identify the Role of Acetyl-CoA**: Acetyl-CoA is involved in the synthesis of fatty acids and steroids. It serves as a building block for these compounds.

3. **Evaluate the Options**:
- **Option 1: Protein**: Acetyl-CoA is not primarily involved in protein synthesis. Therefore, this option is incorrect.
- **Option 2: Fatty Acid**: Acetyl-CoA is indeed a precursor for fatty acid synthesis. This option is correct.
- **Option 3: Organic Acids**: While Acetyl-CoA can be involved in the metabolism of organic acids, it is not a direct precursor for their synthesis. Thus, this option is incorrect.
- **Option 4: Carbohydrates**: Acetyl-CoA does not serve as a precursor for carbohydrate synthesis. Therefore, this option is also incorrect.

4. **Conclusion**: Based on the evaluation of the options, the correct answer is that Acetyl-CoA is a precursor of fatty acid synthesis.

**Final Answer**: Acetyl CoA is a precursor of **fatty acid** synthesis.
