The family of neurotoxins  
 
A large amount of highly homologous snake neurotoxins have been sequenced (>60), and can be grouped into two major classes. Short neurotoxins are between 60-62 amino acids long, and consist of four <scene name='Sandbox_174/Newscene/2'>Disulphide Bonds</scene>

Elapidae neurotoxins bind specifically and tightly in a non-covalent manner to the nicotinic acetylcholine receptors in cholinergic synapses of their victims. This prevents normal neurotransmitter-induced channel opening, which in turn blocks postsynaptic membrane depolarization<ref name="main">Love. A.R (FINISH)</ref>.
