apart from birds. Testosterone and estradiol circulate in the bloodstream, loosely bound mostly to serum albumin (~54%), and to a lesser extent bound

synonymously with "globular protein". However, albumins are also globular proteins, but are not globulins. All other serum globular proteins are globulins. All
