Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections.

WebFischer projections Definition Fischer projection is a suitable method for the representation of long-chain molecules like carbohydrates in which there are so many … Chiral molecules can be described as ones with a set of stereoisomers or left and right-handed enantiomers. As defined by Lord Kelvin, a molecule has chirality “if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself.” In other words, a chiral molecule is asymmetrical in the sense that it's mirror image will not be an exact copy of itself. Chirality is key to understand in many fields such as drug development as one enantiomer of a drug may caus…
WebFischer projection of D-glyceraldehyde. Like most carbohydrates, simple aldoses have the general chemical formula C n (H 2 O) n. Because formaldehyde (n=1) and glycolaldehyde (n=2) are not generally considered to be carbohydrates, the simplest possible aldose is the triose glyceraldehyde, which only contains three carbon atoms.
WebJul 5, 2024 · In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. The two horizontal bonds are directed toward the viewer (forward of the stereogenic carbon). The two vertical bonds are directed behind the central carbon (away from the viewer). iowa public service commissionWebFigure \(\PageIndex{8}\): Conversion of the Fischer projection of D-glucose to the Haworth projection of ß-D-glucose.
