Question

How do you draw enantiomers with Fischer projection?

Answer 1

You draw the groups on the other side of the vertical line,

Enantiomers are mirror images of each other.

If you have the structure for one isomer, you just draw its mirror image to get the enantiomer.

With a Fischer projection, you simply exchange for the groups on either side of the vertical line.

The structure on the left is the Fischer projection of D-glucose.

In L-glucose, all the `"OH"` groups that were on the right are now on the left, and those that were on the left are now on the right.
