Fischer Projection

A two-dimensional representation of a three-dimensional organic molecule by projecting bonds from a chiral center, used to depict stereochemistry.

Chiral

Describes a molecule that cannot be superimposed on its mirror image, often resulting in molecules that have different biological activities.

Asymmetric Carbons

Carbon atoms bonded to four different groups, creating a chiral center and leading to possible optical isomerism.
