H-Gly-Pro-Arg-Pro-OH醋酸盐可与纤维蛋白原（K | i | = 400 mM）中的聚合位点（D结构域）结合，并防止纤维蛋白原聚集和纤维蛋白聚合。它也可以作为抗凝剂。研究表明，在纤维蛋白原切割过程中，还有α，β和γ纤维蛋白原多肽的蛋白水解作用，这也可能包括纤维蛋白肽的初步去除。 H-Gly-Pro-Arg-Pro-OH Acetate Salt can bind to the polymerization site (D domain) in fibrinogen (K|i|= 400 mM) and prevent fibrinogen aggregation and fibrin polymerization. It also acts as an anticoagulant. Research shows that there is additional proteolysis of α, β and γ fibrinogen polypeptides during the cleavage of fibrinogen, which may also include the initial removal of fibrinopeptides.
