•Macromolecules are the
BASIC STUFF OF LIFE!!
Carbohydrates-Lipids- Proteins – Nucleic Acids
They Begin as
MONOMERSsimple form and
build into their
longer form
POLYMERS
Carbohydrates

depends on carb.
Structure C, H, O
EXAMPLES: MonomerSugar, Glucose, Fructose
Disaccharide-Sucrose
PolysaccharideGlycogen, Starch,
Cellulose
Polymer-
Lipids
 Used for energy or cell
structure
 or insulation, warmth
 Structure varies
Monomer: Amino Acid
Proteins
 Used in almost all cell
function, many have
very specific functions
 Only one with
Nitrogen
 Structure: C, H, O, N
and sometimes S
Polymer: PROTEIN
Monomer: Nucleotide
Nucleic Acids
 Used to build RNA and
DNA (our genetic code)
 Nucleic Acids participate
in the process of Protein
Synthesis.
Polymer: Nucleic Acid – DNA
