Question

Quizplus · Accepted Answer

Lipids are defined as organic molecules that are not soluble in water but are soluble in nonpolar solvents such as chloroform or ether. Steroids are a type of lipid and are not soluble in water, making option B the correct choice. While steroids do play a role in cell membranes, they are not essential components like phospholipids or cholesterol. Steroids are not made of fatty acids; instead, they are composed of carbon rings. Steroids are not hydrophilic compounds, which are soluble in water. While steroids may contribute to atherosclerosis, this is not a defining characteristic of lipids.
