 Despite the clear distinction between dinosporin and other resistant biopolymer groups, very little is known about the actual structure of dinosporin.A recent study has suggested that dinosporin present in cysts of "Lingulodinium polyedrum" does not contain significant amounts of long chain aliphatics, nor is it primarily aromatic, but that it is a highly crosslinked carbohydrate-based polymer.Furthermore, dinosporin may be taxon specific as species within the same genus exhibited different compositions, so that dinosporin may be more accurately thought of as a suite of related but chemically distinguishable biopolymers.
