The primary form of coisol in the plasma is
The majority of coisol is bound to a specific carrier protein, coicosteroid binding globulin (CBG), while smaller amounts are bound nonspecifically to albumin. Few, if any, coisol receptors would be expected in the plasma and transthyretin binds primarily thyroxine.Ref: Guyton; 13th edition
