Organic compounds containing an amino group and carboxyl group on the same carbon atom are called

Options

A. Fatty acids
B. Nucleic acids
C. Amino acids
D. Carbohydrates

Answer

To solve the question, "Organic compounds containing an amino group and carboxyl group on the same carbon atom are called," we can follow these steps:

### Step 1: Understand the Functional Groups
- Identify the two functional groups mentioned in the question: the amino group (-NH2) and the carboxyl group (-COOH).

### Step 2: Identify the Structure
- Recognize that both the amino group and the carboxyl group can be attached to the same carbon atom. This structure is characteristic of a specific type of organic compound.

### Step 3: Recall the Definition
- Recall that compounds with both an amino group and a carboxyl group on the same carbon are known as amino acids. Amino acids are the building blocks of proteins.

### Step 4: Analyze the Options
- Review the options given:
- **Fatty acid**: These contain a carboxyl group but do not have an amino group.
- **Nucleic acid**: These are polymers made from nucleotides and do not contain both groups on the same carbon.
- **Amino acid**: This is the correct answer as it contains both the amino and carboxyl groups on the same carbon.
- **Carbohydrate**: These are made up of carbon, hydrogen, and oxygen, and do not contain amino or carboxyl groups.

### Step 5: Conclusion
- Based on the analysis, the correct answer is **amino acid**.

### Final Answer
Organic compounds containing an amino group and carboxyl group on the same carbon atom are called **amino acids**.
