Definitions:

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.

Fischer Projection

A two-dimensional representation of a 3D organic molecule by projection, depicting stereochemistry at chiral centers.

Stereochemical Relationship

The relative spatial arrangement of atoms within molecules that dictates their chemical behavior and reactions, focusing on how these relationships affect molecular properties.
