[Structural organization of the fibrinogen molecule].

A brief review of the chemical structure of the fibrinogen molecule, its proteolytic fragmentation, physicochemical and functional properties of proteolytic fragments is presented. The previous notions on the structure of the fibrinogen molecule are considered as well as new data obtained by the methods of scanning microcalorimetry, electron microscopy and by other methods which permit suggesting some models for structural organization of the fibrinogen molecule.
