单词	haemocyanin
释义	haemocyanin /ˌhiːmə(ʊ)ˈsʌɪənɪn / (US hemocyanin) noun [mass noun] Biochemistry A protein containing copper, responsible for transporting oxygen in the blood plasma of arthropods and molluscs.It is intriguing that crustaceans seem to express either hemoglobin or hemocyanin but not both proteins.... One grasshopper embryo has a protein that closely resembles hemocyanin in sequence, but no oxygen binding studies to confirm its function have yet been done. The ontogeny of crustacean hemocyanin, the copper-based oxygen transport protein, has been studied in relatively few species, including Nephrops norvegicus and Homarus americanus. Origin Mid 19th century: from haemo- 'of blood' + cyan + -in1.
