WebApr 13, 2024 · Nature is not always ambidextrous: it sometimes favors one hand, e.g., in the chirality of amino acids. In a recent issue of Cell Reports Physical Science, Wang and Sugiyama demonstrate the transformation of a crystal from achiral to chiral, where the hand of the crystal can be selected by the hand of circularly polarized light.

WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).
