Co*ag`u*la"tion (?), n. [L. coagulatio.]


The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat. Coagulation is generally the change of an albuminous body into an insoluble modification.

<-- by heat is due to denaturation of protein. -->


The substance or body formed by coagulation.
