Α-Amanitin

Chemical compound

α-Amanitin (alpha-Amanitin) is a cyclic peptide of eight amino acids. It is possibly the most deadly of all the amatoxins, toxins found in several species of the mushroom genus Amanita, one being the death cap as well as the destroying angel, a complex of similar species, principally A. virosa and A. bisporigera. It is also found in the mushrooms Galerina marginata, Lepiota subincarnata and Conocybe filaris. The oral LD50 of amanitin is 100 μg/kg for rats.
