3.4. Cobra venom (cobratoxin) is a small basic protein (Mr = 7000). It contains 62 amino acids in a single chain, cross-linked by four disulfide bonds. The toxin comprises 10% of the venom by weight. It is a neurotoxin that is secreted by glands of the cobra snake and injected into its prey via immobile, grooved fangs.

How does a snake get its venom into the victim?
The venom, once produced, is delivered by a duct to the fang base, where it is transported into the victim either by a groove in the fang, or through a fang duct. Contraction of muscles around the gland producing intra-glandular pressure are the usual mode of venom transport, often allowing the snake to “fine-tune” how much venom is expended in…
