Which of the following acts as transpoing protein for progesterone?
Transcoin serve as a transpoing protein for progesterone. Other hormones bound to transcoin are coisol and other coicosteroids. Steroid hormones are hydrophobic and are mostly bound to large proteins called steroid binding proteins (SBP), which are synthesized in the liver. Sex hormone binding globulin is a glycoprotein bound to sex hormones, testosterone and 17 beta estradiol. Catecholamine and most peptide hormones are soluble in plasma and are transpoed as such.
