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 ... Hemocyanine is een eiwit dat in het bloed van sommige geleedpotigen voorkomt. Hemocyanine heeft een vergelijkbare werking als hemoglobine met als grote verschil, dat hemoglobine een ijzerion bevat en hemocyanine een koperion. In geoxideerde toestand heeft het hemocyanine een blauwe kleur, waardoor het bloed blauw gekleurd is.
