### Cocaine Molecular Structure

#### Description

This diagram displays the chemical structure of cocaine. It is a complex organic compound with the following notable features:

- **Molecular Composition:**
  - The structure includes various functional groups and bonds, demonstrating a rich diversity of chemistry.
  - Key atoms are labeled, including carbon (C), hydrogen (H), nitrogen (N), and oxygen (O).

- **Highlighted Groups:**
  - **Me (Methyl Group):** A functional group attached to the nitrogen atom, indicated by "Me."
  - **OMe (Methoxy Group):** Attached to the carbon-oxygen double bond.

- **Ring System:**
  - The structure includes a bicyclic system with numbered carbon atoms (1 through 5), which represent different positions within the molecule. These numbers are likely references to specific sites of reactivity or significance in chemical reactions.

- **Functional Groups:**
  - Ester groups characterized by the presence of carbonyl (C=O) and ether (O) bonds.
  - A phenyl group (an aromatic benzene ring) is present, contributing to the compound's aromaticity and influencing its chemical properties.

This molecular configuration is crucial for understanding cocaine's biochemical behavior and its interaction with biological systems.
