"Chemical structure of palytoxin shows a very long branched carbon chain with multiple connected ring systems. Numerous hydroxyl groups, oxygen atoms, double bonds, and amide linkages appear throughout the molecule. Solid and dashed wedge bonds indicate stereochemistry at many positions. The structure forms an extended irregular arrangement with repeating oxygen containing functional groups."
