Hemicyanines
WebHemocianina. Les hemocianines (en anglès: Hemocyanins o haemocyanins) són proteïnes que transporten oxigen a través del cos d'alguns animals invertebrats. Pertanyen al grup metal·loproteïna i contenen àtoms de coure enllaçats reversiblement amb una molècula d'oxigen (O₂). Després de l' hemoglobina, és la segona molècula de ...
