Definitions:

Molecular Chaperones

Proteins that help other proteins fold properly. Although chaperones do not dictate the folding pattern, they make the process more efficient.

Tertiary Structure

The overall three-dimensional structure of a protein molecule, formed by the folding and coiling of its secondary structures into a unique shape.

Protein Folding

The physical process by which a protein chain acquires its three-dimensional structure, which is critical for its biological function.

Asymmetric Carbons

Asymmetric carbons are carbon atoms bonded to four different atoms or groups, leading to molecules that can exist in non-superimposable mirror images, or enantiomers.
