WebThermo Scientific instruments, equipment, software, services and consumables empower scientists to solve for complex analytical challenges in pharmaceutical, biotechnology, … WebA Fischer projection is a drawing of a 3D molecule as a flat structure. The chiral carbons are represented by crossed lines. In addition to carbohydrates, it is useful for other molecules that have two or more chiral carbons. Fischer projections are useful for differentiating between enantiomers, diastereomers, and meso compounds.
Two older prefixes still commonly used to distinguish diastereomers are threo and erythro. In the case of saccharides, when drawn in the Fischer projection the erythro isomer has two identical substituents on the same side and the threo isomer has them on opposite sides. When drawn as a zig-zag chain, the erythro isomer has two identical substituents on different sides of the plane (anti). The names are derived from the diastereomeric four-carbon aldoses erythrose (a syrup) and WebD, all represent pairs of diastereomers because they are non-superimposable and are not mirror images. A few rules regarding Fischer projection that will be explored further in the exercises are as follows: 1. Fischer projections may be turned 180°. 2. Fischer projections may not be turned 90°. 3.

WebDiastereomers that contain two or more stereogenic carbon atoms but differ in configuration at only one stereogenic center are called epimers. Thus, the diastereomers d -glucose and d -galactose are epimers because they differ in configuration only at C-4. d -Glucose and d -mannose are epimers that differ in configuration at C-2.
WebFischer projection: We use two ways to visualize three dimensional CHOs on a two dimensional piece of paper. The first is the Fischer projection. ... Steroisomers, Enantiomers, Diastereomers, Meso Compounds: Stereoisomers are compounds having the same molecular formula and same structure, but different orientations of their atoms in …
WebWe know stereoisomers that are not mirror images are called Diastereomers. They are either geometrical isomers or compounds containing two or more chiral centres. A Diastereomer is called erythro if its Fischer projection shows similar groups on the same side of the molecule. chirrotWebDiastereomers are stereoisomers that are not related as object and mirror image and are not enantiomers.
