Macromolecule Jigsaw Instructions:
1. With your pod, research 1 of the
following macromolecules:
proteins, lipids, carbohydrates,
nucleic acids.
2. In foldable (see p. 157) or note
form research the following:
Macromolecule: _____________
 Monomers (building blocks)
 Functions within body
 Where do they come from/how
made?
 Examples
3. Report out. All students will
record additional information.
MM: Proteins
- Sub-units: Amino Acids
- Function: Can facilitate
chemical reactions within the
body, transport O2 and CO2 in
bloodstream, contract muscle
tissue, provide structure for
organs and tissues.
- Come from: All cells perform
protein synthesis by putting
together amino acids (need
nitrogen!!)
- Ex’s: Enzymes, nails, muscle
tissue, hair
Lipids:
 Sub-units-> fatty acid chains,
glycerol groups
 Function: Long-term energy
storage; cellular and organ
protection
 Come from- body makes some
naturally; animal meats, dairy
products and vegetable oils
 Ex’s: peanut oil, ear wax,
steroids, hormones, adipose
tissue (fatty animal tissue)
Carbohydrates:
 Consists of- saccharides
 Function- Provides short term
energy storage, can act as
receptors on cell membranes.
 Obtained mostly through plants
and some through animal
products (dairy, liver contains
glycogen)
 Ex’s: Fructose, wheat, sucrose,
lactose, starch, cellulose (plant
cell walls), glucose
Nucleic Acids:
 Consist of nucleotides (sugar,
phosphate & nitrogen base)
 Regulates protein synthesis
and carries genetic information
for all organisms.
 Passed down through
heredity cells make more
through nutrient uptake and
cell division (DNA replication)
 Ex’s: Deoxyribonucleic Acid
and Ribonucleic Acid
