WebMay 17, 2024 · The small chiral bias produced in proposed processes is unlikely to lead to a homochiral state and some prebiotic mechanism is still required for enantiomeric amplification (Blackmond 2010). We propose a new mechanism that might result in chirality excess, assuming that amino acids were synthesized on dust particles in interstellar space. WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.
