The architecture of starch blocklets follows phyllotaxic rules
Francesco Spinozzi; Claudio Ferrero; Serge Perez · Scientific Reports · 2020 · Geometric macromolecular model with scattering comparisons
Original publication · Original publication · Original publication
Recorded summary
The authors construct golden-angle spiral ellipsoids from starch-related structural units and calculate scattering patterns. Similarities to reported blocklet features motivate a proposed amylopectin architecture.
Recorded limitations
The golden-angle arrangement is imposed in the construction. Agreement with selected structural and scattering features does not uniquely identify the native architecture or establish a biosynthetic mechanism.
Evidence and provenance
