Sites of hormone production
... Once they arrive at a target cell, peptide and steroid hormones have different mechanisms of action. The difference is based on fat-solubility, which determines whether or not the hormone can penetrate the target cell's plasma membrane (which is a lipid bilayer). Peptides are not fat soluble, so the ...
