Verified step by step guidance

1. Identify the structure of D-Mannose from the Fischer projection. D-Mannose is an aldohexose, which means it has an aldehyde group at the top and six carbon atoms in total.
2. Convert the Fischer projection to a bond-line structure. Start by drawing the carbon backbone. For D-Mannose, this will be a six-carbon chain.
3. Place the aldehyde group (CHO) at the top of the chain, which corresponds to the first carbon in the Fischer projection.
4. Add the hydroxyl groups (OH) to the appropriate carbons based on the stereochemistry shown in the Fischer projection. For D-Mannose, the OH groups on the second and fourth carbons are on the right, and the OH group on the third carbon is on the left.
5. Ensure the stereochemistry is correctly represented in the bond-line structure. Use wedges and dashes to indicate the orientation of the OH groups: wedges for groups coming out of the plane and dashes for groups going into the plane.
