Kershner-Macromolecules

Carbohydrates, nucleic acids, proteins, and lipids are essential macromolecules with distinct structures and functions. Carbohydrates, composed of carbon, hydrogen, and oxygen, provide quick energy, store energy, and create structural components in plants, animals, arthropods, and fungi.
