(a)
Interpretation:
The Fischer projection formula of L-lyxose is to be drawn.
Concept introduction:
Fischer projections are shorthand notations used to represent the configurations about asymmetric carbons in a molecule, particularly sugars. The molecule is drawn with the carbonyl
(b)
Interpretation:
To be drawing the Fischer projection of l-talose.
Concept introduction:
Fischer projections are shorthand notations used to represent the configurations about asymmetric carbons in a molecule, particularly sugars. The molecule is drawn with the carbonyl functional group at the top. Perpendicular intersecting lines represent a carbon atom typically a chiral center. Horizontal bonds point toward the viewer, whereas vertical bonds point away from the viewer. In Fischer projection of L form, the OH group of the highest numbered asymmetric carbon is on the left side of the projection.
