What are the functions of : Carbohydrates, Proteins, Lipids, Nucleic acids?

• Answer:

  carbohydrates: storage and transport of energy and structural components Proteins: Many proteins are enzymes that catalyze biochemical reactions, and are vital to metabolism. Protein is also necessary in animals' diets, since they cannot synthesise all the amino acids and must obtain essential amino acids from food. Lipids: Have many functions in living organisms including nutrients, energy storage, structural components of cell membranes, and important signaling molecules. The smooth endoplasmic reticulum also processes these lipids, which store energy. Nucleic Acids: Carry genetic information or form structures within cells.
