Which of the following sets have combination of an acidic, basic and netural amino acids repestively?

Options

A. Glutamate- Lysine- Glycine
B. Arg-Asp-Val
C. Asp-Val-Phe
D. Phe-Lys-Arg.

Answer

To determine which set contains a combination of an acidic, basic, and neutral amino acid respectively, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Acidic Amino Acids**:
- Acidic amino acids have side chains that can donate protons (H+ ions). The two primary acidic amino acids are:
- **Aspartate (Asp)**
- **Glutamate (Glu)**
- These amino acids have carboxylic acid groups that make them acidic.

2. **Identify Basic Amino Acids**:
- Basic amino acids have side chains that can accept protons. The three main basic amino acids are:
- **Arginine (Arg)**
- **Lysine (Lys)**
- **Histidine (His)**
- These amino acids contain nitrogen groups that can bind protons, giving them a positive charge.

3. **Identify Neutral Amino Acids**:
- Neutral amino acids have side chains that are neither acidic nor basic. Common neutral amino acids include:
- **Alanine (Ala)**
- **Glycine (Gly)**
- **Leucine (Leu)**
- These amino acids have both a carboxylic group and an amino group, which balance each other out, resulting in neutrality.

4. **Evaluate the Given Options**:
- We need to check the options provided to find a combination that matches the sequence: Acidic, Basic, Neutral.
- For example, if we have an option like **Glutamate (acidic), Lysine (basic), Glycine (neutral)**, we can see that it follows the correct sequence.

5. **Conclusion**:
- After evaluating the options, the correct combination that includes an acidic amino acid, a basic amino acid, and a neutral amino acid is **Glutamate, Lysine, Glycine**.

### Final Answer:
The correct set that contains an acidic, basic, and neutral amino acid respectively is **Glutamate, Lysine, Glycine**.
