Plasma proteins do not merely maintain colloid osmotic pressure or serve as passive carriers, but instead constitute a core functional layer in the circulatory system for metal coordination, inflammatory reprogramming, and injury buffering. Transferrin, ceruloplasmin, albumin, haptoglobin, and ...
Transferrin (TRF) is a key iron-transport β-globulin in body fluids. It binds ferric iron (Fe³⁺) with high affinity and enables cellular uptake and delivery through receptor-mediated pathways.
Albumin and transferrin are two essential functional proteins in human plasma. Albumin plays central roles in maintaining plasma colloid osmotic pressure and transporting a broad spectrum of low-molecular-weight ligands, whereas transferrin is a key regulator of iron metabolism and is also ...
