Serum Transthyretin

Serum Transthyretin

Transthyretin, known also as prealbumin or thyroxine-binding prealbumin, serves as a transport protein for thyroxine, and as a carier protein for RBP (Section 16.2.4). It has a longer half-life (i.e., 2d) (table 16.3) and a slightly larger body pool (0.010 g/kg body weight), compared to RBP, although the  sensitivities of these two serum proteins to protein deprivation and treatment are similar. Transthyretin has a high content of the amino acid tryptophan and a high proportion of essential to nonessential amino acids. Thus it can be used as an indicator of the availability of essential amino acids in the body (Spiekerman, 1993.).
