Biological amino acids are exclusively homochiral due to prebiotic chemical selection
the verdict
SUPPORTED
the evidence backs this
confidence 83/100
Current prebiotic chemistry models and experiments demonstrate that small initial enantiomeric imbalances in amino acids can be amplified through processes like sublimation, autocatalysis, and kinetic resolution to achieve biological homochirality.
