β-amanitin
Sign in to saveAlso known as beta-amanitin
β-Amanitin ('''beta-Amanitin') is a cyclic peptide comprising eight amino acids. It is part of a group of toxins called amatoxins, which can be found in several mushrooms belonging to the genus Amanita. Some examples are the death cap (Amanita phalloides) and members of the destroying angel complex, which includes A. virosa and A. bisporigera. Due to the presence of α-Amanitin, β-Amanitin, γ-Amanitin and epsilon-Amanitin these mushrooms are highly lethal to human beings. right|thumb|Amanita phalloides''

== Toxicity == The lethal dose of amanitoxins is 0.1 mg/kg of body weight of humans. The average Amanita mushroom contains 3–5 mg of amanitoxins, so one 40–50 g mushroom could kill an average adult. The U.S. Occupational Safety and Health Administration (OSHA) permits a time-weighted average exposure of up to 5 mg/m3 of β-Amanitin dust.
