Abstract: Three different crystalline amylose–glycerolmonostearate(GMS) complexes with increasing thermal stability can be distinguished:type I, type IIa, and type IIb. All complexes consist of GMS-loadedamylose helices that pack hexagonally into lamellar habits. The complexmelting points are proportional to the thickness of the lamellae anddepend on the amount of water in the system. For type I complexes,SAXS experiments reveal folded amylose chains and a lamellar thicknessgoverned by the presence of two stretched lipid molecules per amylosehelix. In the conversion from type I to type IIa complexes, the shortamylose chains unfold and assume a stretched conformation, which increasesthe number of aligned lipid molecules within the helices to four.In type IIb complexes, another pair of lipid molecules is added. Thederived quantitative relation between crystal layer thickness, watercontent and melting point for amylose–GMS complexes also predictsthe melting points of other amylose–monoacyl glycerol complexes.
