Fischer projections
WebAbout this unit. 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. WebJan 22, 2024 · A Fischer projection in organic chemistry is a 2D representation, using vertical and horizontal lines, of a 3D molecule. Explore Fischer projection examples, interpretations, and rotations.

WebDec 15, 2024 · a) Fischer and Haworth projections. Carbohydrates, also commonly referred to as “sugars,” can be represented in many forms. One such form is a Fischer projection, a two-dimensional representation of a molecule that gives three-dimensional information. The horizontal lines of a Fischer projection are equivalent to wedges: … WebExplanation: Groups connected to both the front and back carbons are drawn using sticks at 120° angles. A sawhorse projection is similar to a Newman projection, but it shows the carbon-carbon bond that is hidden …
WebFischer projections were originally developed by German chemist Emil Fischer for work on carbohydrate (sugar) chemistry. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection. http://www.pwconserve.org/wildlife/insects/spiders/darkfishing.html
WebApr 10, 2024 · Fischer projections are a way of drawing molecules in two dimensions. The most important thing to remember when drawing a Fischer projection is that the horizontal lines represent bonds that are coming out of the plane of the paper, and the vertical lines represent bonds that are going into the plane of the paper. This can be a bit confusing ... WebThe Fischer projection of glucose has simplified the representation of the three dimensional structure of those chiral carbons.
