Options

A. Isomers
B. Polymers
C. Tautomers
D. Synonyms

Answer

To answer the question about phosphoglyceraldehyde and dihydroxyacetone phosphate, we need to analyze the characteristics of these two compounds.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- Phosphoglyceraldehyde (often referred to as glyceraldehyde-3-phosphate or G3P) and dihydroxyacetone phosphate (DHAP) are both intermediates in the glycolytic pathway.

2. **Understand the Definitions**:
- **Isomers**: Compounds that have the same molecular formula but different structural arrangements.
- **Polymers**: Large molecules made up of repeating subunits (monomers).
- **Tautomers**: Isomers that can readily interconvert by the movement of a hydrogen atom and a double bond.
- **Synonyms**: Different names for the same compound.

3. **Compare the Molecular Formulas**:
- Both phosphoglyceraldehyde and dihydroxyacetone phosphate have the same molecular formula (C3H7O6P). This indicates that they could be isomers.

4. **Analyze the Structure**:
- Although they have the same molecular formula, their structures differ. Phosphoglyceraldehyde has an aldehyde group, while dihydroxyacetone phosphate has a ketone group. This structural difference confirms they are isomers.

5. **Conclusion**:
- Since both compounds have the same molecular formula but different structural arrangements, they are classified as **isomers**.

### Final Answer:
Phosphoglyceraldehyde and dihydroxyacetone phosphate are **isomers**.
