Primary function: dissolves and carries nutrients, removes waste, regulates body temp, acts as solvent/lubricant, sources: beverages, fruits, veggies, body is 75% water. Insulation: protection, carbon, oxygen, hydrogen, saturated: any fat solid at room temperature worse than unsaturated ex: fried food, unsaturated: fats liquid at room temperature oils better for health, triglyceride- key energy source, 3 fatty acids.
