• Function: 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.
• KEGG Pathway: Thyroid hormone synthesis (hsa04918)
• Reactome Pathway:
  Recycling of bile acids and salts (R-HSA-159418)
  HDL-mediated lipid transport (R-HSA-194223)
  Scavenging of heme from plasma (R-HSA-2168880)
  Platelet degranulation (R-HSA-114608)
