Carbohydrate is

Options

A. polymer of fatty acids
B. polymer of amino acid
C. polyhydroxy aldehyde or etone
D. None

Answer

**Step-by-Step Text Solution:**

1. **Understanding Carbohydrates**: Carbohydrates are organic compounds made up of carbon (C), hydrogen (H), and oxygen (O) atoms. They are one of the four major biomolecules essential for life.

2. **Identifying the Options**: The question provides four options:
- A) Polymer of fatty acid
- B) Polymer of amino acid
- C) Polyhydroxy aldehyde or ketone
- D) None

3. **Analyzing Each Option**:
- **Option A**: Polymer of fatty acid - This is incorrect because fatty acids form lipids, not carbohydrates.
- **Option B**: Polymer of amino acid - This is also incorrect as amino acids form proteins, not carbohydrates.
- **Option C**: Polyhydroxy aldehyde or ketone - This is the correct option. Carbohydrates can be classified as polyhydroxy aldehydes (like glucose) or polyhydroxy ketones (like fructose).
- **Option D**: None - This option is incorrect since option C is valid.

4. **Conclusion**: The correct answer is option C, which states that carbohydrates are polyhydroxy aldehydes or ketones.

5. **Examples of Carbohydrates**: Common examples include sugars (like glucose and fructose), starch, and fiber. These compounds are often sweet-tasting and play crucial roles in energy storage and supply.
