Explination:

Waxes, steroids, phospholipids, and triglycerides are all types of lipids. While their structures and functions all vary, they are all made of hydrocarbon chains that are hydrophobic. Triglycerides (fats) are the body's energy storage molecules. Steroids make up sex hormone and cholesterol. Phospholipids make up the cell membrane, separating the cytoplasm for the environment.

There are four major classes of Biomolecules - Carbohydrates, Proteins, Nucleic acids and Lipids

Carbohydrate for energy, protein for building cells and other fuction like making structures like haemoglobin hair ... etc, Nucleic acid for carrying hareditary material and lipids for insulation just to mention few
