What type of toxin is Amatoxin?
What type of toxin is Amatoxin? Several different types of naturally occurring toxicants exist in poisonous mushrooms. The most hazardous of the mushroom toxins are the Group I toxins. Amatoxin is the best example and is produced by Amanita phalloides, the so-called death cap mushroom. What do Phallotoxins do? Phallotoxins are cyclic heptapeptides that inhibit actin polymerization and depolymerization, with resulting cell membrane dysfunction. How are Phallotoxins absorbed? phalloides are amatoxins and phallotoxins, but phallotoxins are not absorbed by the gastrointestinal route, so toxicity following ingestion of mushrooms is due to amatoxins. Amatoxins are excreted into the bile but undergo...
