Homoyessotoxin is a marine biotoxin produced by certain species of dinoflagellates, particularly Protoceratium reticulatum. It belongs to the yessotoxin group of polyether toxins, which are known to accumulate in shellfish. Although homoyessotoxin is less toxic than some related compounds, it can still pose a risk to human health when consumed in contaminated shellfish, leading to gastrointestinal disturbances and other symptoms. This toxin is a focus of research in marine toxicology and food safety to ensure the safe consumption of shellfish.
