,10. Function of carbohydrates: source of fuel once broken down
into monomer form (monosaccharide)
11. Structural components of other molecules including
nucleic acids, glycoproteins, glycolipids, ATP, and related
nucleotides: carbohydrates 12. Required in greater amounts
than any other nutrient: carbohydrates

steroids, glycolipids 22. Sources of lipids: eggs, dairy products,
avocados, coconut, fatty fish, nuts, and seeds
23. Functions of proteins: muscle contraction, structural
components, globular proteins, plasma proteins, buffer ph of body
