Amino acids are produced from

Options

A. proteins
B. fatty acids
C. essential oils
D. `alpha`-keto acids

Explanation

**Step-by-Step Solution:**

1. **Understanding Amino Acids**: Amino acids are the building blocks of proteins. They are organic compounds that contain both an amino group (-NH2) and a carboxyl group (-COOH).

2. **Identifying the Source of Amino Acids**: The question asks from which substances amino acids are produced. The options provided include proteins, fatty acids, essential oils, and alpha-keto acids.

3. **Analyzing Each Option**:
- **Option 1: Proteins**: Proteins are polymers made up of long chains of amino acids linked by peptide bonds. When proteins undergo hydrolysis (the process of breaking down into smaller units in the presence of water), they yield amino acids. Therefore, proteins are a direct source of amino acids.

- **Option 2: Fatty Acids**: Fatty acids are long-chain hydrocarbons with a carboxylic acid group. They do not yield amino acids upon hydrolysis; instead, they produce carbon dioxide, water, and energy through metabolic pathways.

- **Option 3: Essential Oils**: Essential oils are complex mixtures of volatile compounds produced by plants. They do not contain amino acids and do not yield them upon breakdown.

- **Option 4: Alpha-Keto Acids**: Alpha-keto acids are organic compounds that can participate in various metabolic processes, but they do not directly yield amino acids.

4. **Conclusion**: Based on the analysis, the only option that produces amino acids is **Option 1: Proteins**.

5. **Final Answer**: Amino acids are produced from proteins.
