- Summary table
Type of compound | Action on the body | Family/Species |
---|---|---|
Acetylcholinesterases (AChE) | Might cause tetanic paralysis | Colubridae, Elapidae |
Arginine esterases | Predigest prey | Viperidae |
Bradykinin-potentiating peptides (BPP) | Pain, hypotension, immobilize prey | Viperidae |
C-type lectins | Modulate platelet activity, prevent clotting | Viperidae |
Cysteine-rich secretory proteins (CRiSP) | Induce hypothermia, immobilize prey | Colubridae, Elapidae, Viperidae |
Disintegrins | Inhibit platelet activity, promote hemorrhaging | Viperidae |
Hyaluronidases | Increase interstitial fluidity, aiding the dissemination of venom from the bite site | Elapidae, Viperidae |
L-amino acid oxidases (LAAO) | Cell damage/apoptosis | Elapidae, Viperidae |
Metalloproteinases (MPr) | Hemorrhage, myonecrosis, believed to predigest prey | Atractaspididae, Colubridae, Elapidae, Viperidae |
Myotoxins | Myonecrosis, analgesia, immobilize prey | Viperidae |
Nerve growth factors | Might cause cell apoptosis | Elapidae, Viperidae |
Phosphodiesterases (PDE) | Might cause hypotension, shock | Colubridae, Elapidae, Viperidae |
PhospholipaseA2 (PLA2) | Myotoxicity, myonecrosis, damage to cell membranes | Colubridae, Elapidae, Viperidae |
PLA2-based presynaptic neurotoxins | Immobilize prey | Elapidae, Viperidae |
Prothrombin activators | Disseminated intravascular coagulation (DIC: small clots form throughout body, leading to uncontrolled bleeding), which can be fatal | Elapidae |
Purines and pyrimidines | Might cause hypotension, paralysis, apoptosis, necrosis, immobilization of prey | Elapidae, Viperidae |
Sarafotoxins | Myocardial ischemia (reduced blood flow to heart), increase blood pressure, disturb heart rhythm | Atractaspididae |
Serine proteases | Hemostasis disruption, hypotension, immobilize prey | Colubridae, Viperidae |
Three-finger toxins (3FTx) | Rapid immobilization of prey, paralysis, death | Colubridae, Elapidae |
