Racemization of Amino Acids on an evolutionary time scale. Alpha methyl amino acids cannot racemize
Decarboxylative transamination. Note that the final product shown can be protonated from either face, generating a racemic mixture after hydrolysis of the imine.
Formation of alpha keto acids. The product shown above is believed to be oxidized to the final alpha keto acid by oxidation by iron oxide, as oxygen was not present on prebiotic earth.
The conformation of the alpha-methyl amino acid favors protonation on the top face of the molecule, leading to the D-enantiomer. Hydrolysis of the decarboxylation product generates the D-amino acid.
