When you’re bitten by a venomous snake, you’re not dealing with a single toxin—you’re facing a complex biochemical weapon containing 20-100 different proteins and peptides.

Snake venom composition varies dramatically between species and even individual snakes, creating unique molecular fingerprints that scientists study using advanced techniques like mass spectrometry.

The main components include phospholipases A2 that destroy cell membranes, metalloproteinases causing hemorrhaging, serine proteinases disrupting blood clotting, and three-finger toxins targeting your nervous system.

These toxins work together synergistically, attacking multiple body systems simultaneously to immobilize prey efficiently.

Modern proteomic analysis reveals that while individual venoms contain 50-200 proteins from over 100 families, 90% come from just 8-10 major toxin groups—but understanding how these molecular machines evolved reveals surprising medical breakthroughs.

Snake Venom Composition Overview

You encounter one of nature’s most sophisticated chemical weapons when you’re bitten by a venomous snake – a complex cocktail containing 20 to over 100 different proteins and peptides designed for prey capture.

These venoms vary dramatically between species and even within the same snake due to environmental factors, age, and genetic differences.

Complexity of Snake Venom

When examining snake venom composition, you’ll discover nature’s most sophisticated biochemical weapons system.
