Oxidation of fibrinogen with hypochlorite inhibited the fibrin network self-assembly even at the lowest concentration of the oxidant. The analysis of the results of protein electrophoresis at this hypochlorite concentration showed the absence of fragmentation of the protein and covalent cross-linking of its chains. The study of the areas responsible for the conversion of fibrinogen into fibrin by mass spectrometry showed that they are not subject to oxidative damage. However, we identified oxidized amino acid residues, which could affect the protofibril aggregation.

UI MeSH Term Description Entries
D008297 Male Males
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D005260 Female Females
D005337 Fibrin A protein derived from FIBRINOGEN in the presence of THROMBIN, which forms part of the blood clot. Antithrombin I
D005340 Fibrinogen Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products. Coagulation Factor I,Factor I,Blood Coagulation Factor I,gamma-Fibrinogen,Factor I, Coagulation,gamma Fibrinogen
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012973 Sodium Hypochlorite It is used as an oxidizing and bleaching agent and as a disinfectant. (From Grant & Hackh's Chemical Dictionary, 5th ed) Antiformin,Clorox,Sodium Hypochlorite (Solution),Hypochlorite, Sodium
