Hormones are grouped into three groups based on general structures as follows:Steroid hormones are fat-soluble molecules made from cholesterol. Among these are the three major sex hormones groups: estrogens, androgens, and progesterone. Males and females make all three, just in different amounts. Steroids pass into a cell's nucleus, bind to specific receptors and genes, and trigger the cell to make proteins.Amino acid derivatives, such as epinephrine, are water-soluble molecules derived from amino acids (the building blocks of protein). These hormones are stored in endocrine cells until needed. They act by binding to protein receptors on the surface of the cell or by binding to protein inside the cell.Polypeptide hormones like insulin, growth hormone and prolactin consist of long chains of amino acids, from several to 200 amino acids long. They are stored in endocrine cells until needed to regulate such processes as metabolism, lactation, growth, and reproduction.So, the correct answer is option D.
