X-ray crystal structure of the hexadepsipeptide cyclo (Gly-Lac-Lac)2 with lactyl β-turns

Two crystal forms of the depsipeptide cyclo(Gly-Lac-Lac)2 have been characterized. One of them only gives small crystals; from the other form we have determined the structure by single crystal X-ray diffraction. The general cyclic shape of the molecule is
