hemocyanin /he·mo·cy·a·nin/ (-si´ah-nin) a blue copper-containing respiratory pigment occurring in the blood of mollusks and arthropods. hemocyanin [hē′mōsī′ənin] an oxygen-carrying protein molecule present in certain lower animals, particularly arthropods and mollusks. The molecule is similar to the hemoglobin molecule of human blood but uses copper atoms, rather than iron, and is less efficient than hemoglobin in requiring many more atoms to bind a single molecule of oxygen.
