Most lipid hormones are derived from cholesterol and thus are structurally similar to it, as illustrated in Figure 18.2.The primary class of lipid hormones in humans is the steroid hormones. Cholesterol travels through the blood on proteins called “lipoproteins.” Two types of lipoproteins carry cholesterol throughout the body: LDL (low-density lipoprotein), sometimes called “bad” cholesterol, makes up most of your body’s cholesterol.High levels of LDL cholesterol raise your risk for heart disease and stroke. While waxes are long hydrocarbon chains with one or two functional groups, cholesterol and its steroid derivatives contain various hydrocarbon ring structures. Cholesterol also is needed to make vitamin D, hormones (including testosterone and estrogen), and fat-dissolving bile acids. 213 34 Cholesterol is kept in balance by homeostatic mechanisms: higher dietary intake leads to reduced synthesis in the body.
