For the cluster geometries of hydrated pyruvate and organic acids (including pyruvic acid), we show that for all clusters containing one to four water molecules, a complete conservation of the water network structure with respect to the pure water cluster is preserved. However, upon introduction of ions into the pyruvic acid-containing clusters and pyruvate-containing clusters, we show that the water structure of the clusters are perturbed significantly compared to the organic acid clusters without ions and the reference systems.
