Amides are different from amino acids as they contain more

Options

A. (a) hydrogen
B. (b) oxygen
C. (c) nitrogen
D. (d) carbon

Explanation

To solve the question "Amides are different from amino acids as they contain more," we will analyze the components of both amides and amino acids to determine the correct answer.

### Step-by-Step Solution:

1. **Define Amides**: Amides are organic compounds that contain a carbonyl group (C=O) directly attached to a nitrogen atom (N). The general structure of an amide is R-CO-NR'R'', where R, R', and R'' can be hydrogen or hydrocarbon groups.

2. **Define Amino Acids**: Amino acids are organic compounds that serve as the building blocks of proteins. Each amino acid contains both an amine group (-NH2) and a carboxylic acid group (-COOH). The general structure of an amino acid is R-CH(NH2)-COOH.

3. **Compare the Composition**:
- **Nitrogen Content**: Amino acids contain one nitrogen atom in their amine group. In contrast, amides contain at least one nitrogen atom connected to the carbonyl carbon, and they can have more nitrogen atoms depending on their structure.
- **Hydrogen, Oxygen, and Carbon Content**: Both amides and amino acids contain hydrogen, oxygen, and carbon. However, the key difference lies in the nitrogen content.

4. **Identify the Key Difference**: The primary distinction between amides and amino acids is the amount of nitrogen present. Amides generally have more nitrogen compared to amino acids.

5. **Select the Correct Option**: Based on the analysis, the correct answer to the question is option C: nitrogen.

### Final Answer:
Amides are different from amino acids as they contain more nitrogen. Therefore, the correct answer is **option C: nitrogen**.
