Fischer projection
Noun
Meaning
Fischer projection (plural Fischer projections)
A two-dimensional representation of a three-dimensional organic molecule by projection, used mainly in organic chemistry and biochemistry.
Examples
The Fischer projection is a systematic way of drawing the skeletal formula of an acyclic monosaccharide so that the handedness of each chiral carbon is well specified.
In the Fischer projection, one of the two glucose isomers has the hydroxyl at left on C3, and at right on C4 and C5; while the other isomer has the reversed pattern.
In the Fischer projection, the D - and L - prefixes specifies the configuration at the carbon atom that is second from bottom: D - if the hydroxyl is on the right side, and L - if it is on the left side.
