Main function = energy storage (short-term)
Other uses = structure, transport, and signaling
Found in = sugars and starches
Composed of = C, H, O
Monomer = monosaccharides = single sugar
molecules
Ex. Glucose (main fuel for cell), galactose (in milk), fructose (in fruit)
Polymer = polysaccharides = larger sugar molecules
Ex. Starch (how plants store sugar), glycogen (how animals store sugar), cellulose (structural support in plant cell walls)
Energy storage = 4 calories/gram
Body can access and break it down easily, thus it is typically the first thing your body will break down to get energy when you need it!

# data[].attributes.body
Main function = energy storage (long-term)
Other uses = insulation, protection, and structure
Found in = fats, oils,
phospholipids (in the cell membrane), steroids
Composed of = C, H, O
Monomer = fatty acids
Polymer = triglycerides
Energy storage = 9 calories/gram
When your body runs out of easy-to-access
carbs, it will break down lipids next for energy

# data[].attributes.body
Main function = no “main function” because
proteins do SO MUCH! They run your body!
Enzymes that control the rate of biochemical reactions
Hormones that regulate cell processes (Ex. Insulin)
Structurally And so much more
Found in = meats, nuts, and dairy
products, but many are made by your body
Composed of = C, H, O, N, P, S
Monomer = Amino acids
Polymer = Polypeptide
Amino acids linked together by a peptide bond
Energy storage = 4 calories/gram
Proteins do SO MUCH besides for the body that they are usually the last resort if energy is needed
Proteins are the most diverse macromolecule
in terms of structure AND function
4 levels to their structure
Form dictates function

# data[].attributes.body
Main function = informational molecules that store,
transmit, and express our genetic information;
contain the instructions for making proteins
Found in = DNA and RNA
You get them from your parents not your food!!
Composed of = C, H, O, N, P
Monomer = Nucleotides
Adenine, Guanine, Thymine, Cytosine, and Uracil
These are made up of:
5-Carbon sugar
Phosphate group
Nitrogen-containing base
Polymer = Nucleic acid = DNA or RNA
Energy storage = 0 calories/gram
They are NEVER broken down as a source of
energy!!
