Medical Definition of Complement 3d
1.
An inactivated fragment of complement 3b (c3b). Factor h makes c3b susceptible to factor I (formerly called kaf, c3binf, or enzyme 3b inactivator) to form ic3b. Then factor I and a trypsin-like proteolytic enzyme further cleave ic3b into c3c and c3dg. Serum proteases degrade c3dg into complement 3d (c3d) and c3g.
