B. 51 mol of carbon dioxide and 49 moles of water
C. 98 mol of carbon dioxide and 102 moles of water
D. 49 mol of carbon dioxide and 51 moles of water

Answer

To solve the question regarding the oxidation of one mole of tripalmitin, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Tripalmitin**:
- Tripalmitin is a triglyceride composed of three palmitic acid molecules. The chemical formula for palmitic acid is C16H32O2. Therefore, the formula for tripalmitin (which is derived from three palmitic acid molecules) is C51H98O6.

2. **Understand the Oxidation Process**:
- During the oxidation of fats (like tripalmitin), the fatty acids are broken down to produce carbon dioxide (CO2) and water (H2O). The general reaction can be summarized as:
\[ \text{C}_n\text{H}_m + O_2 \rightarrow CO_2 + H_2O \]

3. **Calculate the Products of Oxidation**:
- For the complete oxidation of tripalmitin (C51H98O6), we need to determine how many moles of CO2 and H2O are produced.
- The complete oxidation of one mole of tripalmitin yields:
- **Carbon Dioxide (CO2)**: 51 moles
- **Water (H2O)**: 49 moles

4. **Determine the Oxygen Consumption**:
- The oxidation process will consume oxygen. For tripalmitin, the stoichiometry indicates that approximately 72.5 moles of O2 are consumed during the oxidation.

5. **Calculate the Respiratory Quotient (RQ)**:
- The RQ can be calculated using the formula:
\[ RQ = \frac{\text{CO2 produced}}{\text{O2 consumed}} = \frac{51}{72.5} \approx 0.7 \]
- This indicates that the oxidation of tripalmitin is less than complete oxidation of carbohydrates (which has an RQ of 1).

6. **Final Answer**:
- Based on the calculations, the oxidation of one mole of tripalmitin releases 51 moles of CO2 and 49 moles of H2O.

### Conclusion:
The correct answer to the question is that the oxidation of one mole of tripalmitin releases **51 moles of CO2 and 49 moles of H2O**.
