CARBON!
*All living organisms contain carbon!
Chemistry of Carbon: Carbon can bond with many elements including other Carbons and can make 4 bonds!
MONOMER AND POLYMERS
Monomers are single units and when you get lots of monomers together, you get a polymer
This process is called polymerization
CARBOHYDRATES
Made up of C, H, and O in a ratio of 1:2:1
Used by living things as their main source of energy
COMPOSITION OF POLYMERS
Monomer for carbohydrates: glucose
Polymer for carbohydrates:-starch-cellulose-glycogen
Where do we see Glucose in our daily lives?Honey is Glucose
with minor things added by the bees.
If you put two glucose together (dissaccharides), you can get several different things
Sucrose Lactose FructoseC12H22O11 C12H22O11 C12H22O11
If you stick several Glucose Molecules together we get………Complex carbs also known as
polysaccharidesFunction: long term storage of glucose used for different things
Starch:Used by plants to store excess
glucose
Cellulose:Used by plants as
a building material
Glycogen:Used by animals to store excess
glucose
What can you eat that has more energy than Carbs?
Lipids (fats) can store enough energy that they can even hold a flame!Plants store fat as liquids.
Animals store fat as solids
Lipids:-Composed of C and H -Known as fats, oils, waxes, and steroids-At least 1 C=C double bond makes afat unsaturated
Lipid Composition:
A Glycerin Molecule
This acts as a connector for:Three Fatty acids The fatty acids contain several carbon groups that store energy in their bonds.
Uses for Lipids:
1. Energy Storage:
We use fatty acids for energy when we work out and carbs. have been used up2. Structure of cells:
Every cell has a cell membrane that is made of Phospholipids.3. Messengers:Steroids are lipids that carry messages through the blood stream
If I am trying to get strong, what do I eat?
Proteins!Proteins are found in meat, nuts, beans
Monomer: Amino acids: 20 different molecules that combine to make all proteins These are just two
PROTEIN USES:
Control the rate of reactions (these are called enzymes)
Regulate cell processesForm bones and muscleTransport substancesFight disease
EXAMPLES OF PROTEIN POLYMERS:
MONOMER
The monomer of a nucleic acid is a nucleotide
A nucleotide is composed of a sugar, phosphate, and nitrogen base
The polymer of a nucleotide is a DNA or RNA strand
DNA stands for deoxyribonucleic acid RNA stands for ribonucleic acid
