Name two acidic amino acids.

Explanation

To answer the question, "Name two acidic amino acids," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Amino Acids**: Amino acids are organic compounds that serve as the building blocks of proteins. Each amino acid has a basic structure that includes an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable R group (side chain).

2. **Identifying Acidic Amino Acids**: Acidic amino acids are characterized by having an additional carboxyl group in their R group, which gives them acidic properties. This extra carboxyl group can donate a proton (H+), making the amino acid acidic.
