Could Vulcans' green blood actually work biologically?
Original: RE: https:// mstdn.social/@compoundchem/117 399522978507602 Can Vulcans have green blood and still run around and behave
Chemists and biology fans are debating whether the fictional Vulcan physiology from Star Trek is plausible: green blood based on copper rather than iron. Commenters note that copper-based blood proteins like hemocyanin really exist in animals such as horseshoe crabs and octopuses, so green blood is not inherently impossible, though whether oxygen transport could sustain an active human-like body remains contested.
Why now: A science communicator's explanation of the chemistry behind Vulcan blood prompted fans to discuss the real biology of copper-based blood pigments.
