Study Notes
Major Classes of Nutrients
- Six primary classes: carbohydrates, lipids (fats), proteins, minerals, vitamins, and water.
Water (H2O)
- Non-energy yielding; contains no calories.
- Essential for metabolic reactions and overall bodily functions.
- Regulates body temperature effectively.
- Comprises approximately 60% of adult body mass.
Minerals
- Non-energy yielding micronutrients; do not provide calories.
- Made up of indestructible chemical elements.
- Includes 16 known essential minerals, such as copper, iron, cobalt, and chromium.
Vitamins
- Non-energy yielding micronutrients that assist in metabolic processes.
- Crucial for the release of energy from carbohydrates, fats, and proteins.
- Includes various types such as vitamins A, B, C, D, and E.
Carbohydrates (CHO)
- Energy-yielding macronutrients, providing calories for energy.
- Composed primarily of carbon, hydrogen, and oxygen.
- Constitutes the majority of most diets, essential for energy supply.
Proteins
- Organic, energy-yielding macronutrients vital for growth and repair of tissues.
- Made of carbon, hydrogen, oxygen, and nitrogen.
- Serve as building blocks for various structures in the body.
Lipids (Fats)
- Energy-yielding macronutrients that provide essential energy.
- Function as protective agents, providing insulation and cushioning for organs.
- Important for nutrient storage and are a key component of cell membranes and the immune system.
