== 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 ==
The Anderson-type hexamolybdoaluminate functionalized with lauric acid (LA), (TBA)3[Al(OH)3Mo6O18{(OCH2)3CNHCOC11H23}].9H2O (TBA-AlMo6-LA, where TBA = tetrabutylammonium), was prepared via two synthetic routes and characterized by thermogravimetric and elemental analyses, mass spectrometry, IR and (1)H NMR spectroscopy, and powder and single-crystal X-ray diffraction. The interaction of TBA-AlMo6-LA with human serum albumin (HSA) was investigated via fluorescence and circular dichroism spectroscopy. The results revealed that TBA-AlMo6-LA binds strongly to HSA (63% quenching at an HSA/TBA-AlMo6-LA ratio of 1:1), exhibiting static quenching. In contrast to TBA-AlMo6-LA, the nonfunctionalized polyoxometalate, Na3(H2O)6[Al(OH)6Mo6O18].2H2O (AlMo6), showed weak binding toward HSA (22% quenching at a HSA/AlMo6 ratio of 1:25). HSA binding was confirmed by X-ray structure analysis of the HSA-Myr-AlMo6-LA complex (Myr = myristate). These results provide a promising lead for the design of novel polyoxometalate-based hybrids that are able to exploit HSA as a delivery vehicle to improve their pharmacokinetics and bioactivity.
