Using modern electronic structure methods for evaluating interatomic forces and a chemical oriented heuristic approach, Giuseppe Lanza and Maria A. Chiacchio, in e26161, constructed the very first hydration shell around aliphatic amino acids. The water‐amino acid interactions are dominated by strong hydrogen bonds involving charged groups. To minimize the cavity size and to prevent water‐water hydrogen bonding loss, the water molecules around hydrophobic side chain adopt a shape resembling the one found in crystal structure of gas clathrate hydrates. This is exemplified in the cover image for the hydration shell of valine. DOI: 10.1002/qua.26161

Giuseppe Lanza和Maria A. Chiacchio使用现代电子结构方法评估原子间作用力和化学导向的启发式方法，在e26161中围绕脂肪族氨基酸构建了第一个水合壳。水-氨基酸相互作用主要由涉及带电基团的强氢键决定。为了最大程度地减小空腔尺寸并防止水-水氢键合损失，疏水性侧链周围的水分子采用类似于气态笼形水合物水合物晶体结构的形状。这在缬氨酸水合壳的封面图像中得到了举例说明。DOI：10.1002 / qua.26161
