WebContinued C1 activation of the classical complement pathway leaves patients in a chronic hemolytic state 1,2 ACTIVATED C1 TRIGGERS THE CLASSICAL COMPLEMENT PATHWAY, LEADING TO POTENTIALLY SERIOUS CHRONIC HEMOLYSIS 1 * C1 amplifies the activation of C3, resulting in extravascular hemolysis and chronic … WebBiochem/physiol Actions. Complement C3 is the third and most abundant component of the complement pathway. It plays a central role in complement activation, being involved in both the classical and alternative pathways. C3 or its proteolytic fragments mediate many biological functions such as opsonization and anaphylatoxin activities.
