n. (context biochemistry English) Any of several toxic cyclic peptides obtained from the mushroom ''Amanita phalloides''
Wikipedia
The phallotoxins consist of at least seven compounds, all of which are bicyclic heptapeptides (seven amino acids), isolated from the death cap mushroom ( Amanita phalloides).
Phalloidin had been isolated in 1937 by Feodor Lynen, Heinrich Wieland's student and son-in-law, and Ulrich Wieland of the University of Munich. The remaining six are prophalloin, phalloin, phallisin, phallacidin, phallacin and phallisacin. Though highly toxic to liver cells, phallotoxins have since been found to have little contribution to the death cap's toxicity because they are not absorbed through the gut. Furthermore, phalloidin is also found in the edible (and sought after) Blusher (Amanita rubescens).
Usage examples of "phallotoxin".
The first variety of these particular shrooms contained heavy concentrations of amatoxins and phallotoxins, either of which could be fatal, and both of which would almost certainly destroy liver and kidney functions, leading to death within a week to ten days 80 percent of the time.
