PPT-The Biology of Weaponized Toxins

Written by Raymond Saiz Robert Crannage and Amorray Overview History of Toxins Ricin Cyanide Adrenaline Symptoms Chemical EffectsStructure Where its found Ricin on a Molecular Level One molecule of Ricin contains two long chains When separated these chains are not dangerous However when they are bonded Ricin molecules containing both chains can cause cell death in humans. Although many blooms are merely an aesthetic nuisance some species of algae produce toxins that kill fish shellfish humans livestock and wildlife Pigmented blooms of toxin producing marine algae are often referred to as red tides Fig 361 Proliferati Structural organization of AB-toxins. Proteolytic cleavage of the toxin isrequired, in many cases, for activity, and such cleavage often occurs inthe region between the A (black) and the B (gray) subu Human Gastrointestinal Disorders.
