Webb1 sep. 2002 · The thyroid hormones are >99% bound to thyroxine‐binding globulin, thyroxine‐binding prealbumin and albumin in plasma. The free hormone component within plasma is in equilibrium with the protein‐bound hormone, and it is this free fraction which accounts for the hormone's biological activities. WebbThe location of steroid and thyroid hormone binding differs slightly: a steroid hormone may bind to its receptor within the cytosol or within the nucleus. In either case, this binding generates a hormone-receptor complex that moves toward the chromatin in the cell nucleus and binds to a particular segment of the cell’s DNA.
