Within your body, there are two major categories of hormones. One category is the steroid (or lipid-soluble) hormones, and the other category is referred to as nonsteroid (or water-soluble) hormones, which are composed of proteins or, in some cases, just

amino acids. Estrogen and testosterone are examples of steroid hormones, whereas insulin is an example of a nonsteroid hormone. A researcher heats estrogen, testosterone, and insulin to a very high temperature. After heating the hormones, the researcher tests to determine whether they still work properly. She finds that estrogen and testosterone still function, but insulin does not. Based on the chemical nature of these molecules, explain why insulin no longer functions. What will be an ideal response?
