Bellwork:
Compare and Contrast Carbohydrates vs Lipids
Carbohydrates
Lipids
Five functions of proteins include:
• Controlling the rate of
reactions (enzymes).
• Regulating cell
processes (enzymes).
• Forming bones and
muscles.
• Transporting
substances into or out
of cells.
• Helping to fight
disease.
Proteins are polymers of molecules
called amino acids.
More than 20
different
amino acids
are found in
nature.
The instructions for arranging amino
acids into many different proteins is
stored in DNA.
A protein has
four levels of
organization.
The function of a protein is determined by
its shape.

THIS!
Now let’s review… The four groups of organic
compounds found in living things are:
• Carbohydrates
• Lipids
• Nucleic acids
• Proteins
Functions:
Structure:
•Peptide bonds connect the amino acids
•Enough amino acids connected together
will cause the protein to fold and create a
new shape
Elements:
Controlling the rate of reactions (enzymes).
Regulating cell processes (enzymes).
Forming bones and muscles.
Transporting substances into or out of
cells.
Helping to fight disease (antibodies).
Function is determined by shape!
Good to know:
•Carbon (C), Hydrogen (H),
Oxygen (O), Nitrogen (N)
Protein
Monomer:
•Amino acid
•Examples: Serine (Ser), Proline
(Pro)
•The R
group
changes.
•The instructions to make
proteins is stored in DNA
Polymer:
•Protein (also called a
polypeptide)
•Examples: insulin, alcohol
dehydrogenase
