Unique Insulin Produced by Sea Snails May Provide Insights on Insulin Function and Energy Metabolism

Researchers have found that cone snails produce a venom containing a unique form of insulin that causes small fish on which the snails prey to go into hypoglycemic shock. The snail insulin could prove useful for studying how different forms of insulin control blood sugar and energy metabolism. It consists of 43 amino acid building blocks, fewer than any known insulin. The new findings are published in PNAS.
