Configuration CHO CHO H C-OH HO- C-H CH2OH CH2OH D-Glyceraldehyde L-Glyceraldehyde Fischer projection formulas Solid wedge- shaped bonds CHO CHO point toward the H-C-OH HO-C-H readers,dasted CH2OH CH2OH wedges point D-Glyceraldehyde L-Glyceraldehyde away. Perspective formulas
Configuration Solid wedgeshaped bonds point toward the readers, dasted wedges point away
prefix D or L refers to the configuration of the highest numbered asymmetric carbon (the asymmetric carbon from the carbonyl carbon)
• prefix D or L refers to the configuration of the highest numbered asymmetric carbon (the asymmetric carbon farthest from the carbonyl carbon)
