The ups and downs . High‐resolution X‐ray data revealed interesting proline ring puckering of hydroxyproline diastereoisomers, which could be in an atypical state depending on position selectivity. AlloHyp at the Y position in one sequence showed up‐puckering (left), while Hyp at the X position in another showed down‐puckering (right). On the other hand, Hyp at the Y position showed up‐puckering as expected.
