Question
**Title: Understanding the Form of Alanine at Low pH**

**Instructions:**

1. **Suggest the Form of Alanine (Sidechain R = CH3) at Low pH:**
   - At low pH values, the environment is highly acidic. In such conditions, the amino acid alanine, with its sidechain R group (CH3), will gain protons (H+). The amino group (NH2) will become protonated to form NH3+, and the carboxyl group (COOH) will generally remain protonated as COOH because of the high concentration of hydrogen ions in the solution.

2. **No Stereochemistry is Required for This Answer:**
   - When drawing the molecular structure, you do not need to show the spatial arrangement of atoms (stereochemistry); a simple structural formula will suffice.

3. **Drawing the Molecule:**
   - Use the provided canvas tools to draw the structure of alanine at low pH.
   - Select the appropriate buttons from the Tools toolbar to draw the bonds.
   - Pick atoms from the Atoms toolbar and place them correctly in the structure.
   - Utilize the Advanced Template toolbar for any additional specialized requirements, such as indicating charges.
   - Ensure that all hydrogen atoms are included in your drawing.

**Example of Steps to Draw Alanine at Low pH:**

1. Start with the carbon backbone: Draw a central carbon atom.
2. Attach the sidechain R (CH3) to the central carbon.
3. Attach the amino group (NH3+) to the central carbon.
4. Attach the carboxyl group (COOH) to the central carbon.
5. Ensure that all hydrogen atoms are drawn to complete the structure.

**Visual Aid:**

_Below is a simple depiction to guide your drawing:_

    H
     |
NH3+ - C - CH3
     |
  COOH

This illustrates alanine in its protonated form at a low pH level, reflecting an acidic environment where all possible protonation occurs.
