Kuhn was fascinated by the unusual structural symmetry of the carbon bonds that form the molecular backbone of polyene pigments.
Carotene was only the most highly visible of Kuhn's polyene studies.
Ironically, in 1930, when impurities were hampering Kuhn's structural and functional work on polyene pigments, it was
It is a lipid-soluble polyene chain with a polar region at either end.
MLn fragments, has been used by my research group to analyze cluster bonding and the equilibrium geometries and conformational preferences of olefin and polyene metal carbonyl complexes.
Kuhn's sixth report on conjugated double bonds already contains structure determinations of polyene dyes from vegetable materials.
In the proposed mechanism for the early stage of 10-membered enediyne biosynthesis, CalE8 produces a carbonyl-conjugated polyene with the assistance of
Moreover, computational docking suggested that the substrate-binding channel binds a polyene substrate that contains a single cis double bond at the C4 / C5 position, raising the possibility that the C4 = C5 double bond in the enediyne moiety could be generated by the iterative polyketide synthase.
