WebApr 7, 2024 · Toxicity is the degree to which a chemical substance or a specific mixture of substances can lead to damage to an organism. It can refer to the whole organism's effect, such as an animal, plant, or bacterium, and the effect on the organism's substructure, such as an organ or cell (cytotoxicity) like the liver (hepatotoxicity). WebMay 27, 2024 · 1 Answer. From the diagram, it appears that local and global aromaticity are related to how the aromatic coupling is arranged in the macrocycle. Local aromaticity is characterized by aromatic coupling within individual rings or regions with little conjugation between. Such structures are planar within their aromatic rings/regions, but generally ...
