MeSH definition : The larger fragment generated from the cleavage of C5 by C5 CONVERTASE that yields
COMPLEMENT C5A and C5b (beta chain alpha' chain, the residual alpha chain, bound
by disulfide bond). C5b remains bound to the membrane and initiates the spontaneous
assembly of the late complement components to form C5b-8-poly-C9, the MEMBRANE ATTACK
COMPLEX.;
