Biologically active steroids are transported in the blood simply by albumin sex hormone-binding globulin (SHBG) and corticosteroid-binding globulin (CBG). tasks in controlling steroid access to target cells and cells. They bind steroids with high (~nM) affinity and specificity with SHBG binding androgens and estrogens and CBG binding glucocorticoids and progesterone. Both are glycoproteins that are… Continue reading Biologically active steroids are transported in the blood simply by albumin
