albumin
The term normally refers to serum albumins, the major protein components of the serum of vertebrates. They have a single polypeptide chain, with multidomain structure containing multiple binding sites for many lipophilic metabolites, notably fatty acids and bile pigments. In the embryo their functions are fulfilled by alpha-fetoproteins. See bovine serum albumin. The viability of analbuminaemic mutants (those deficient in albumin) raises serious questions about the biological role of albumin.
