Relevance. Rating Newest Oldest. Best Answer: Lipid soluble hormones are usually steroid hormones (have a structure containing a pattern of 6-6-6-5 fused carbon rings). They cross the cell membrane and bind to some receptor in the cytosol, causing it to translocate to the nucleus where it can regulate genetic events.
Plasma Membrane Hormone Receptors. Amino acid-derived hormones and polypeptide hormones are not lipid-derived (lipid-soluble or fat-soluble); therefore, they cannot diffuse through the plasma membrane of cells. Lipid-insoluble hormones bind to receptors on the outer surface of the plasma membrane, via plasma membrane hormone receptors. Unlike steroid hormones, lipid-insoluble hormones do not directly affect the target cell because they cannot enter the cell and act directly on DNA.
