2: The correct stereochemistry of only one stereocenter is indicated on the above structure. The actual stereochemistry of methyl glucoside is such that, when it is in a chair form, aill of the substituents fall in the equatorial positions, except for the -OMe, which is found in the axial position. Given this information, draw a clear, correct representation of methyl glucoside in a chair conformation, with all substituents properly indicated. HO HO, 12 HQ 3. When glucose is in its open-chain form, its stereochemistry can best be represented using a Fischer projection. On the skeleton Fischer projection shown at right, fill in the H and OH groups of the glucose "backbone" with the correct stereochemistry as determined from your structure shown above. H. H- HO HO H

### Stereochemistry and Structural Representation of Methyl Glucoside --- **2. Explanation:** The correct stereochemistry of only one stereocenter is indicated on the above structure. The actual stereochemistry of methyl α-D-glucoside at all five substituents fall in the equatorial positions in the chair form, except for the OMe, which is found in the axial position. Given this information, draw a clear, correct representation of methyl α-D-glucoside in a chair conformation with all substituents properly indicated. **Diagram** (Visual Description): A cyclic chair structure with positions labeled for hydrogen (H), hydroxyl (OH) groups, and a methoxy (OMe) group indicating the specific stereochemistry of methyl α-D-glucoside. --- **3. Fischer Projection:** When glucose is in its open-chain form, its stereochemistry can best be represented using a Fischer projection in which the carbon backbone and attachments are visualized in a linear form. The Fischer projection shown at right requires filling in the H and OH groups for positions 2, 3, 4, and 5 on the glucose backbone with the correct stereochemistry as determined from your structure shown above. **Diagram** (Visual Description): A vertical linear structure with carbon atoms labeled and partially filled in with hydrogen (H) and OH groups indicating an open chain glucose molecule in a Fischer projection. --- These concepts are important for understanding the spatial arrangement of atoms in biomolecules and how they impact the molecule's properties and interactions. Properly drawing chair conformations and Fischer projections is essential for stereochemistry and organic chemistry studies.
