Different nutrients play distinct roles in energy metabolism:
- Carbohydrates: They are broken down into glucose, which is the primary source of energy for the body. - Proteins: These are converted into amino acids, which can be used for energy if carbohydrates are not available. - Fats: They are metabolized into fatty acids and glycerol, which serve as long-term energy reserves.
Nurses need to understand these metabolic pathways to advise appropriate [dietary choices]() and manage [enteral]() or [parenteral]() nutrition for patients who cannot eat normally.
