Episode 4/13: Homochirality // A Course on Abiogenesis by Dr. James Tour

Diving into the science on homochirality, Dr. James Tour teaches the core chemistry concepts of enantiomers and chirality, exposing enormous challenges in the prebiotic synthesis and resolution of the molecules needed for life. By digging into the cited video's only provided reference, Dr. Tour puts ink on paper and shows how the devil is in the details when it comes to proper interpretation of the data. Finally, Dr. Tour touches on the stereoisomeric challenges facing synthetic chemists doing origin-of-life, prebiotic research.
