Two forms of a cyclic molecule , namely a rhomb and a square, are observed for an oligosaccharide, which has four repeating units that consist only of amino sugars (see picture). A relatively high water content (ca. 34 %) can be discerned from the crystals, which were formed from a water/polyethylene glycol solution by utilizing a hanging‐drop crystallization technique.
