Explanation:

Proteins are made of amino acids.

Nucleic Acids are made of nucleotides.

Lipids are made of fatty acids.

Carbohydrates are made of monosaccharides.

Carbohydrates are a source of energy.

Lipids store energy.

Nucleic Acids hold genetic information.

Proteins, carbohydrates, lipids, and nucleic acids are the four major classes of biological macromolecules.

  • Proteins are the polymers of amino acids. Lipids are the polymers of lipid monomers (fatty acid and glycerol). Nucleic acids are the polymers of nucleotides. And, Carbohydrates are polymers of monosaccharides.
  • Examples of proteins-enzymes and some hormones. Examples of carbohydrates -glucose, fructose, starch, and cellulose. Examples of lipids- oil, butter, wax, cholesterol. Examples of nucleic acids- DNA and RNA.
  • The uses of proteins are - enzymes, receptors, structural, energy, etc. The uses of carbohydrates are - energy, storage, and structure. The uses of lipids are protection, energy, storage, and chemical messengers. The use of nucleic acids is genetic information.
