Lipids are hydrocarbon molecules that make up the structure of living beings. Few examples are <u>fats, oils and waxes</u>. Steroids are also a class of lipids but they are not structurally related to other lipids but do share some common properties with them. They are <em>insoluble in water and are hydrophobic</em>( water-repelling).
Explanation:
Lipids are insoluble in water as they are <em>non-polar</em> but soluble in non polar solvents (<em>chloroform</em>). Fat soluble vitamins like <u>A,D,E,K and steroids</u> have a different structure composed of fused four rings.
The most common example of steroid is cholesterol. Cholesterol acts as a precursor for many hormones and other signalling molecules.
Explanation: Steroids are classified as lipids because: I and V
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings.
