Abstract
The structure and biosynthetic pathway of sporopollenin are largely unknown. In 1971, Brooks and Shaw have postulated that sporopollenin is generated from carotenoids and carotenoid esters. This assumption is based on comparartive studies on the naturally occuring sporopollenin and polymers which were synthesized from carotenoids. Both the natural and the synthetic macromolecules exhibit a high level of resistance to acetolysis; both show similar IR spectra and have similar elemental composition.
