albumin Serum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc. Belongs to the ALB/AFP/VDB family. Plasma. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
