Steroid hormones, being lipid-soluble and hydrophobic, readily cross membranes via simple diffusion because they are compatible with the membrane's hydrophobic core.
Steroid hormones are lipid-soluble (hydrophobic), allowing them to easily cross cell membranes by simple diffusion without needing carrier proteins because they are not repelled by the membrane's hydrophobic interior.
