Video: Fischer Projection | Definition & Rules

Video Summary for Fischer Projections

Fischer projections provide a 2D representation of 3D chemical molecules, using a specific system of lines.

In these projections, horizontal lines represent attachments pointing out of the paper toward the viewer, while vertical lines represent attachments pointing away.

The intersection of these lines represents the central carbon atom.

Fischer projections are particularly useful for depicting molecules with multiple stereocenters, such as monosaccharides and amino acids.

• They help quickly visualize the orientation of stereocenters
• They allow easy comparison between similar molecules with different stereochemistry

The video demonstrates how to convert 3D molecular structures into Fischer projections and how to properly rotate these projections while maintaining molecular integrity.
