SUMMARY
The discussion clarifies the structural differences between D-glucose and L-glucose in their Haworth projections. When drawing the Fisher projections, the arrangement of hydrogens and hydroxyl groups alternates, which directly influences the Haworth representation. Specifically, if the hydroxyl group on Carbon 4 of D-glucose is oriented downwards, the corresponding hydroxyl group on L-glucose will be oriented upwards, confirming the opposite orientation in their cyclic forms. This understanding is crucial for accurately representing these monosaccharides in biochemical contexts.
