<prompt> Which set of hormones have nuclear receptor?Estrogen, thyroxine glucagonEstrogen, thyroxine TSHEstrogen, TSH Gonadotropin releasing hormone GnRHNone  <response>: Peptide hormones are proteins that have endocrine functions in living animals.A steroid hormone is a steroid that acts as a hormone. Steroid hormones can be grouped into 2 classes, coicosteroids typically made in the adrenal coex, hence coico- and sex steroids typically made in the gonads or placenta. Within those 2 classes are 5 types according to the receptors to which they bind: glucocoicoids and mineralocoicoids coicosteroids and androgens, estrogens, and progestogens sex steroids. Vitamin D derivatives are a sixth closely related hormone system with homologous receptors. They have some of the characteristics of true steroids as receptor ligands.Ref: Ganong;s review of medical physiology; 24th edition; page no: 302
