Macromolecule Notes
FIRST, RECALL…
What is a monomer? Mono= one -mer = part Building block
What is a polymer? Poly=many -mer=part A polymer is a large molecule consisting of many
smaller subunits bonded together.
CARBOHYDRATES
Monomer: Monosaccharides (simple sugars) known as glucose
Polymer: PolysaccharidesFunction: Provide energy
for respiration & structural support in plant cell walls
Examples: Glucose, fructose, cellulose & starch
Found In: Pasta, fruit, veggies
Elements: CHO
LIPIDS
Composed of: Fatty Acids & Glycerol
Function: Provides insulation, solubility for some vitamins/minerals, waterproofing, part of biological membranes
Examples: Triglycerides, oils, waxes
Found In: Butter, cheese, meats
Elements: CHO
PROTEINS
Monomer: amino acidsPolymer: polypeptidesFunction: almost all
functions of body; muscles, skin, hair; structural support; transport substances; speed up reactions; control cell growth; communicate between cells
Examples: Enzymes, hormones, muscle
Found In: Meat, legumes, nuts
Elements: CHON
NUCLEIC ACID
Monomer: nucleotides
Polymer: nucleic acids
Function: genetic information and all information to produce all cell parts and materials
Examples: DNA & RNA
Found In: Every cellElements: CHOPN
