Which macronutrient includes carbohydrates, proteins, nucleic acids, and lipids?

The category of macronutrients encompasses essential nutrients that are required in larger amounts for the body to function properly. This group includes carbohydrates, proteins, nucleic acids, and lipids, each playing vital roles in bodily processes.

Carbohydrates serve as a primary energy source, proteins are crucial for growth and repair of tissues, nucleic acids (such as DNA and RNA) are fundamental for genetic information storage and transfer, and lipids (fats and oils) are important for energy storage, insulation, and cellular structure. Together, these macronutrients are integral to maintaining health and supporting metabolic processes.

In contrast, vitamins and minerals fall under the category of micronutrients, which are needed in smaller amounts but are still critical for various physiological functions. Vitamins support a range of biochemical reactions, while minerals are key in numerous structural and regulatory functions within the body's systems. Thus, the answer accurately reflects the correct grouping of these fundamental nutrients.
