Step-by-step explanation:
Steroids and some hormones can be made from cholesterol, which is a type of lipid molecule. Phospholipids and polyunsaturated fats are important components of cell membranes, but they don't typically act as hormones. Waxes are lipids that provide a protective coating for plants and animals, but they also don't act as hormones. Ions such as calcium and sodium are important in many physiological processes, including muscle contraction and nerve signaling, but they don't act as hormones either.
