Venom

독(독액)

Definition

A toxic substance injected through a bite or sting, used by some reptiles for prey capture and defense.

Detailed Explanation

Snake venoms are complex cocktails of enzymes, peptides, and proteins — different components cause hemotoxic (blood-destroying), neurotoxic (nerve-blocking), or cytotoxic (tissue-destroying) effects. Venom composition varies within species across geographic ranges, reflecting coevolution with local prey and predators. Paradoxically, many venom components have pharmaceutical applications — ACE inhibitors for hypertension were derived from pit viper venom research. Approximately 100,000 people die from snakebite annually.
