Noncrystal.

Extremely toxic; deadly poison; neurotoxic; cardiotoxic activity; bara-chotoxin that blocks neuromuscular transmission; respiratory paralysis; death.

Potent neurotoxin that activates voltage-gated sodium channels. Shifts voltage-dependent activation to more negative potentials, inactivation is disabled and pore conductance and selectivity are altered (displays increased permeability for NH 4 + , K + and Cs + ions).
