Chemical Nature of Hormones. Chemically, hormones may be classified as either proteins or steroids. All of the hormones in the human body, except the sex hormones and those from the adrenal cortex, are proteins or protein derivatives.ome endocrine glands secrete hormones in response to other hormones. The hormones that cause secretion of other hormones are called tropic hormones. A hormone from gland A causes gland B to secrete its hormone.
Steroid hormones consist of cholesterol, a lipid compound, male and female sex hormone, and cortisol (hormone that stimulates the conversion of amino acids to glucose by the liver). They are compose of compel rings of carbon, hydrogen, and oxygen molecule. And they are not soluble in water but are soluble in fats.he difference between an enzyme and a hormone is due to the purpose they are designed to serve. Hormones control aspects of growth and metabolism such as the breaking of the voice and the development of musculature during puberty in males; and the regulation of the menstrual cycle in females.
