Citrat reduktion
Der reduktive Citratzyklus stellt die Umkehrung des (oxidativen) Citratzyklus dar. Die meisten Enzyme des Citratzyklus werden auch bei diesem Stoffwechselweg verwendet – entgegen dessen Richtung. Im oxidativen Citratzyklus gibt es aber drei irreversible Schritte, die im reduktiven Citratzyklus durch drei spezielle Enzyme umgangen werden: WebSep 25, 2009 · In addition, mortality was reduced in the citrate group, with a reduction in sepsis. Whether this relates to vascular access catheter-acquired infections remains to be determined [ 40 ]. However, it must be remembered that citrate is an extracorporeal regional anticoagulant, and is therefore not a systemic anticoagulant.
