Electron Scattering from Chiral Molecules
It is generally believed that the formation of optically active molecules was a necessary step towards the origin of life. Optically active (or chiral) molecules usually exist in two forms, the l- and d-forms, which are mirror images of each other. In living organisms only one of the two alternative enantiomers is found. Apart from a few exceptions, the amino acids occurring in natural proteins belong to the l-species and sugars to the d-species.
