The primary source of materials for the molecular building blocks of life is food. Through the process of digestion, animals break down food into its basic components such as proteins, carbohydrates, and lipids, which are then used to build and repair cells in the body.
Fatty acids are the building blocks of Lipids (fats). In more detail, the molecular building blocks of a fat are one molecule of glycerol and three molecules of fatty acids.

Amino acids are the building blocks of proteins. Proteins are of primary importance to the continuing functioning of life on Earth.
Neutral fats are esthers of a glycerol molecule, and three fatty acid molecules.

Atoms are important because they form the basic building blocks of all visible matter in the universe.
There are actually four primary "building blocks" of the body. Lipids (fats), carbohydrates, proteins, and nucleic acids.
