receptors for both lipid-soluble and lipid-insoluble hormones are found within the cell and usually within the nucleus. receptors for lipid-soluble hormones are on or in the cell membrane, whereas receptors for lipid-insoluble hormones are inside the cell.
Steroid Hormones. Hormones that have a cholesterol backbone and are not soluble in water due to their lipid structure; steroid hormones are transported through the blood attached to carrier proteins. Steroid hormones penetrate the cell membrane and interact with nuclear receptors that affect DNA transcription.Non-steroid Hormones.ormones that have a cholesterol backbone and are not soluble in water due to their lipid structure; steroid hormones are transported through the blood attached to carrier proteins.
