Structures of mono-unsaturated triacylglycerols. V. The beta'(1)-2, beta'-3 and beta(2)-3 polymorphs of 1,3-dilauroyl-2-oleoylglycerol (LaOLa) from synchrotron and laboratory powder diffraction data.
The crystal structures of the beta'(1)-2, the beta'-3 and the beta(2)-3 polymorphs of 1,3-dilauroyl-2-oleoylglycerol have been solved from powder diffraction data. The packing of the beta(2)-3 polymorph is similar to that of other cis mono-unsaturated triacylglycerols. Both the beta' polymorphs are crystallized in a novel type of packing in which one of the saturated lauroyl chains is packed side-by-side with part of the unsaturated oleoyl chain.
