Macromolecules
* four basic chemicals or compounds make up almost everything
on earth
Carbohydrates
• usable sources of energy/
easily broken down
• sugars, starches, and
cellulose
• monomer =
monosaccharide
• polymer = polysaccharide

Lipids
• includes steroids, fats,
waxes, and oils
• monomer = glycerol
backbone and 3 fatty
acid chains
•Polymer = triglyceride
• used for storage &
structure (cell
membrane)

Proteins
• large molecules - enzymes, hemoglobin, muscles
• monomer: amino acid
• polymer: polypeptide
• more than 1/3 of your body
• many functions: movement, structure, regulation,
transport, nutrition, defense
