Hemovanadin

Hemovanadin is used to refer to the pale green vanabin proteins found in the blood cells, called vanadocytes, of ascidians (sea squirts) and other organisms. It is one of the few known vanadium-containing proteins.[1][2]

German chemist Martin Henze first detected vanadium in ascidians in 1911.<ref name="henze1911" Henze (1911). Untersuchungen fiber das Blut der Ascidien. 1. Die Vanadiumbindung der Blutk6rperchen. Z. Physiol. Chem. 72, 494–50.[3] Unlike hemocyanin and hemoglobin, hemovanadin is not an oxygen carrier.[4]
