Nitrogenous metabolic wastes in our body ar the products of

Options

A. Carbohydrates
B. Proteins
C. Lipids
D. Vitamins

Answer

To answer the question "Nitrogenous metabolic wastes in our body are the products of," we need to analyze the options provided and understand the sources of nitrogenous waste in the human body.

### Step-by-Step Solution:

1. **Identify the Types of Biomolecules**:
- The question presents four options: carbohydrates, proteins, lipids, and vitamins. We need to identify which of these biomolecules can produce nitrogenous waste.

2. **Understanding Nitrogenous Wastes**:
- Nitrogenous wastes are primarily the byproducts of the metabolism of nitrogen-containing compounds. The most common nitrogenous wastes in the body are urea, uric acid, and ammonia.

3. **Analyzing Each Option**:
- **Carbohydrates**: These are composed of carbon, hydrogen, and oxygen. They do not contain nitrogen and therefore do not produce nitrogenous waste.
- **Proteins**: Proteins are made up of amino acids, which contain nitrogen in their amino groups. When proteins are metabolized, they produce nitrogenous wastes, primarily in the form of urea.
- **Lipids**: These are organic compounds made up of carbon, hydrogen, and oxygen. Like carbohydrates, they do not contain nitrogen and do not produce nitrogenous waste.
- **Vitamins**: These are organic compounds that are essential for various metabolic processes but do not contain nitrogen in a way that would produce nitrogenous waste.

4. **Conclusion**:
- Based on the analysis, the only biomolecule that produces significant nitrogenous metabolic waste in the body is **proteins**. The correct answer is therefore **proteins**.

### Final Answer:
Nitrogenous metabolic wastes in our body are the products of **proteins**.
