| Tartalmi kivonat: | During our experimental investigations on the partially dissolved and degraded pollen grains of Ambrosia artemisiifolia L. a degraded regular pentagon biopolymer unit was investigated with two dimensional symmetry operations. The tenfold primary rotation method resulted cyclic molecular clusters on the places of the globular units of the quasi-crystalloid skeleton in Angstrom dimension. This is the first molecular data about the globular units forming the regular pentagon which are the building elements of the metastable quasicrystalloid skeleton. In this contribution we present a short and selected review on the results of the biopolymer organization and symmetry of the sporopollenin. |
