~Biochemistry~
2
MOLECULES are when two or more atoms are bonded together.
ATOMS are the smallest unit of ordinary matter.
Reminder!
3
Ionic bonds are formed when an e- is transferred.
Ionic Bond
Covalent Bonds are formed when an e- is shared.
Strongest Chemical Bond
Covalent Bond

Carbohydrates
Lipids
Protein
Nucleic Acids
5
Mono - means ONE
It is a singular component that makes up the larger structures of macromolecules. Each macromolecule has its own monomers.
Monomer
Poly - means MULTIPLE
A polymer is when two or more monomers bond together to make a larger, more complex macromolecule
Polymer
6
SUGARS
Monomer - monosaccharide
Polymer - Polysaccharide; Disaccharide (TWO monomers)
Sugar's monomers are:
Glucose
Fructose
Galactose
Carbohydrates
7
Multiple Choice
Which of these is likely a sugar base on the last letters of the word?
Cortisol
Lactose
Adenosine Triphosphate
Lactase
8
When two monosaccharides bond, they become a dissacharide. These are simple carbs and are easily broken down sources of energy.
Disaccharides
9
Multiple Choice
How many monomers are joined together to make a disaccharide?

Energy and Structure
The primary functions of carbohydrates is energy storage. Carbohydrates are types of sugars. Outside of energy storage, they can provide structure like the carbohydrate cellulose, which is the indigestible portion of plants.
---words that end in -ose are often sugars
11
Open Ended
What are the two functions of carbohydrates?
12
Fats contain a glycerol and a fatty acid tail.
Lipids (Fats):
13
Store Energy
Like carbohydrates, lipids also have energy. The energy in lipids is not as easy to access, and can also be used as long term storage. It is also used to protect and pad organs, insulate organisms, and help break down certain vitamins (fat soluble).
14
Liquid at room temperature, Oils.
Unsaturated
Solid at room temperature, such as butter, animal fats.
Saturated

Fill in the Blanks
Name two types of fats
Type answer...
17
Multiple Choice
Which of this is NOT a function of fats?
Protect organs
Provide insulation
Store energy
Store genetic material
18
Monomer: Amino Acid
Polymer: Polypeptide
As these chains of amino acids form, the chain folds and creates shapes.
Proteins:
19
Jobs to Perform
Proteins are long chains of amino acids that fold into shapes that do jobs. These jobs can be transporting materials, creating structures, and performing chemical reactions. The proteins that assist in performing chemical reactions are called ENZYMES.
20
Monomer:
Nucleotide (nitrogenous base, pentose sugar, phosphate group)
Polymer:
DNA - Deoxyribonucleic Acid
RNA - Ribonucleic Acid
DNA/RNA/ATP
21
Genetic Material and Batteries
DNA and RNA are two molecules that are the building blocks of genetic materials.
ATP is the molecule created by mitochondria to store and move energy throughout your body.
22
Multiple Choice
Nucleic Acids do which of the following?
Store genetic material and energy
Insulate organs and store energy
Provide structure and store genetic material
Assist with chemical reactions and store genetic material
