The image features two structural formulas of alanine, an amino acid. 

**Left Structure:**

- Depicts the three-dimensional configuration using wedges and dashes.
- The central carbon (α-carbon) is bonded to four different groups: 
  - A methyl group (CH₃)
  - A hydrogen atom (H)
  - A carboxyl group (CO₂H) 
  - An amino group (NH₂)
- The solid wedge indicates that the carboxyl group comes out of the plane towards the viewer.
- The dashed wedge indicates the NH₂ group extends behind the plane.

**Right Structure:**

- Shows a standard representation with:
  - A carboxyl group (CO₂H) positioned at the top
  - An amino group (H₂N) on the left
  - A methyl group (CH₃) at the bottom
  - A hydrogen atom (H) on the right
- This configuration highlights the tetrahedral shape of the molecule around the α-carbon.

Together, these structures illustrate the chirality of alanine, with the left structure particularly emphasizing its three-dimensional nature.
