Glutamine
Glutamine is the most abundant naturally occurring, nonessential amino acid in the human body, and one of the few amino acids that can directly cross the blood–brain barrier. Humans obtain glutamine through catabolism of proteins in foods they eat. In states where tissue is being built or repaired, like growth of babies, or healing from wounds or severe illness, glutamine becomes conditionally essential.
Alpha-Amanitin
"alpha"-Amanitin or α-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 ("Amanita phalloides") 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" and "Conocybe filaris". The oral of amanitin is approximately 0.1 mg/kg for rats.
