Mammals exhibit systemic homochirality of amino acids in L -configurations. While ribosomal protein synthesis requires rigorous chiral selection for L -amino acids, both endogenous and microbial enzymes convert diverse L -amino acids to D -configurations in mammals. However, it is not clear how mammals manage such diverse D -enantiomers.
