The Fisher projection for
Concept introduction:
An asymmetric carbon atom is represented as a cross in Fisher projection. The carbon chain is kept along the vertical line. The groups attached to asymmetric carbon atoms are arranged according to their configuration in Fisher projection.
The enantiomers of a chiral compound can be named with the help of right hand and left-hand configuration.
Aldopentose contains five carbon atoms and is a linear monosaccharide. D-erythrose and L-erythrose are enantiomers of each other. Also, D-threose and L-threose are enantiomers of each other.
