Abstract

Dipeptides may form nanotubular structures with pore diameters in the range 3.2-10 Å. These compounds normally contain at least one and usually two hydrophobic residues, but L-His-L-Ser hydrate, C(9)H(14)N(4)O(4)·3.7H(2)O, with two hydrophilic residues, forms large polar channels filled with ordered as well as disordered water molecules.
