2. Carbohydrate conformation - Wikipedia

   en.wikipedia.org/wiki/Carbohydrate_conformation

   The chair conformation of six-membered rings have a dihedral angle of 60° between adjacent substituents thus usually making it the most stable conformer. Since there are two possible chair conformation steric and stereoelectronic effects such as the anomeric effect, 1,3-diaxial interactions, dipoles and intramolecular hydrogen bonding must be taken into consideration when looking at relative ...

3. Haworth projection - Wikipedia

   en.wikipedia.org/wiki/Haworth_projection

   In chemistry, a Haworth projection is a common way of writing a structural formula to represent the cyclic structure of monosaccharides with a simple three-dimensional perspective. Haworth projection approximate the shapes of the actual molecules better for furanoses —which are in reality nearly planar—than for pyranoses that exist in ...

4. Nuclear magnetic resonance spectroscopy of carbohydrates

   en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

   Carbohydrate NMR spectroscopy is the application of nuclear magnetic resonance (NMR) spectroscopy to structural and conformational analysis of carbohydrates.This method allows the scientists to elucidate structure of monosaccharides, oligosaccharides, polysaccharides, glycoconjugates and other carbohydrate derivatives from synthetic and natural sources.

5. Newman projection - Wikipedia

   en.wikipedia.org/wiki/Newman_projection

   A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [1] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.

6. Fischer projection - Wikipedia

   en.wikipedia.org/wiki/Fischer_projection

   In chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry. The use of Fischer projections ...

   The first woman was elected to lead a country 64 years ago. Here’s a look at where, and when, women have secured national leadership positions since then.

8. Molecular geometry - Wikipedia

   en.wikipedia.org/wiki/Molecular_geometry

   Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.
