Catch a falling star: Peptides from chiral, Cα-methylated α-amino acids (see scheme) found in L enantiomeric excess in meteorites show diastereoselectivity when reacting with racemic proteinogenic amino acids. Accordingly, the prebiotic soup of proteinogenic amino acids may have evolved into a chirally unbalanced system, eventually seeding the homochirality of life.
