Conformation example sentences

Sawhorse projections of eclipsed and staggered conformations of ethane are depicted.Of all the conformations of ethane, the staggered form has the least torsional strain and the eclipsed form, the maximum torsional strain.One such conformation in which hydrogen atoms attached to two carbons are as closed together as possible is called eclipsed conformation and the other in which hydrogens are as far apart as possible is known as the staggered conformation.These are called conformational isomers (conformers).Eclipsed and the staggered conformations can be represented by Sawhorse and Newman projections.The break down of the gradient provides enough energy to cause a conformational change in the F1 particle of the ATPase, which makes the enzyme synthesise several molecules of energy-packed ATP.Thus there are infinite number of conformations of ethane.Alkanes show conformational isomerism due to free rotation along the C–C sigma bonds.Such spatial arrangements of atoms which can be converted into one another by rotation around a C-C single bond are called conformations or conformers or rotamers.Alkanes can thus have infinite number of conformations by rotation around C-C single bonds.Any other intermediate conformation is called a skew conformation.It may be remembered that in all the conformations, the bond angles and the bond lengths remain the same.Out of staggered and the eclipsed conformations of ethane, staggered conformation is more stable as hydrogen atoms are farthest apart.It has not been possible to separate and isolate different conformational isomers of ethane.As already mentioned, the repulsive interaction between the electron clouds, which affects stability of a conformation, is called torsional strain.
