Single Chirality Flip Rewires Glycyrrhizic Acid Hydrogel Assembly and Performance
Start here
A team led by Penglong Wang reports in Angewandte Chemie International Edition that inverting a single C18 stereocenter — the only structural difference between glycyrrhizic acid (GA) and magnesium isoglycyrrhizinate (IGA) — sets off a domino effect through the molecules' self-assembly pathways. The change propagates from how the epimers stack into supramolecular structures to the macroscopic behavior of the hydrogels they form, producing materially different gel performance. Because such hydrogels are candidates for biomedical uses, including drug delivery and tissue-related applications, the work identifies stereochemistry at one carbon as a decisive design lever for tuning gel properties. The findings establish the assembly-performance relationship; which specific biomedical applications best exploit each epimer's gel profile has yet to be mapped out.
