Draw the Fischer projections of the four aldoses. Draw the D-sugar on the left and its L-isomer directly to the right of it.
Understand the Problem
The question is asking to draw the Fischer projections of the four aldoses, specifically the D-sugar on the left and its L-isomer on the right, correctly positioning the hydroxyl groups.
Answer
The Fischer projections show D-sugars on the left and L-sugars on the right for each aldotetrose.
The Fischer projections of the four aldoses, with D-sugars on the left and L-isomers on the right, demonstrate the spatial arrangement of hydroxyl groups for each sugar.
Answer for screen readers
The Fischer projections of the four aldoses, with D-sugars on the left and L-isomers on the right, demonstrate the spatial arrangement of hydroxyl groups for each sugar.
More Information
Aldotetroses like erythrose and threose differ in configuration at the second carbon atom. This affects their chemical properties and biological roles.
Tips
A common mistake is misplacing the hydroxyl group on the wrong side for D/L configurations. Ensure you check the bottom-most chiral center.
