Proteins function in just about everything Structure- skin,
hair, muscle Signaling hormones Transport Enzymes
Slide 11
Proteins are polymers of amino acid monomers There are twenty
different amino acids. Amino acids differ in R groups
Slide 12
Proteins differ in the number and order of amino acids Amino
acids interact to give a protein shape Incorrect amino acids change
a proteins structure and function.
Slide 13
Nucleic acids are monomers of nucleotides Contain C, H, O, N, P
Store and transmit genetic information (DNA and RNA)

Slide 16
Describe at least one function of each group of organic
compound. Why are proteins considered polymers but lipids are not?
What class of macromolecule does the following compound belong
to?
Slide 17
Make a study guide for yourself. List each of the four organic
compounds with Their monomer and polymer (structure) At least two
functions How would you test for this organic compound in the
lab?
Slide 18
Chemical Reactions change substances by breaking and forming
chemical bonds Reactants are changed (what you react) Products are
made (what you produce)
Slide 19
Activation Energy is the amount of energy that needs to be
absorbed to start a chemical reaction (to activate the
reaction)
Slide 20
Release more energy than they absorb (Release heat)
Slide 21
Absorb more energy than they release (take in heat energy feels
cold)
