== Disease ==
[[https://www.uniprot.org/uniprot/ALBU_HUMAN ALBU_HUMAN]] Defects in ALB are a cause of familial dysalbuminemic hyperthyroxinemia (FDH) [MIM:[https://omim.org/entry/103600 103600]]. FDH is a form of euthyroid hyperthyroxinemia that is due to increased affinity of ALB for T(4). It is the most common cause of inherited euthyroid hyperthyroxinemia in Caucasian population.<ref>PMID:8048949</ref> <ref>PMID:7852505</ref> <ref>PMID:9329347</ref> <ref>PMID:9589637</ref>  
== Function ==
[[https://www.uniprot.org/uniprot/ALBU_HUMAN ALBU_HUMAN]] 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.<ref>PMID:19021548</ref>

== Publication Abstract from PubMed ==
Human serum albumin (HSA) is the most abundant protein in the circulatory system. Its principal function is to transport fatty acids, but it is also capable of binding a great variety of metabolites and drugs. Despite intensive efforts, the detailed structural basis of fatty acid binding to HSA has remained elusive. We have now determined the crystal structure of HSA complexed with five molecules of myristate at 2.5 A resolution. The fatty acid molecules bind in long, hydrophobic pockets capped by polar side chains, many of which are basic. These pockets are distributed asymmetrically throughout the HSA molecule, despite its symmetrical repeating domain structure.

Crystal structure of human serum albumin complexed with fatty acid reveals an asymmetric distribution of binding sites.,Curry S, Mandelkow H, Brick P, Franks N Nat Struct Biol. 1998 Sep;5(9):827-35. PMID:9731778<ref>PMID:9731778</ref>
