Which atoms are found in all living things?
CHNOPS
C = carbon
H = hydrogen
N = nitrogen
O = oxygen
P = phosphorus
S = sulfur

Carbon (C)
• The atom that is the basis of all life.
• In organic chemistry, carbon atoms bond to each other to form chains, branches, and rings.
• Common substances made of C:
- Diamonds
- Coal
- Graphite (pencil lead)

Molecules
• many molecules -> macromolecules macro = large molecule = atoms that hook up
• many atoms -> molecules

Macromolecules (Organic Compounds)
• Macromolecules are made of small units called monomers. mono = one
• A monomer is like one link in a chain.
• Many monomers put together make a polymer. poly = many
• A polymer is like a long chain with many links.

4 types of polymers or macromolecules or organic compounds:
• Carbohydrates (sugar)
• Lipids (fat)
• Protein
• Nucleic Acids
![Page 8: Agenda 1. Standards 2. Macromolecules Notes 3. HW: Macromolecules Booklet Warm-Up Question What do you know about carbohydrates, lipids and proteins?](https://reader035.fdocuments.net/reader035/viewer/2022062322/56649f3c5503460f94c5aa6e/html5/thumbnails/8.jpg)
Carbohydrates• Monomer: monosaccharide (one sugar)• Examples: glucose and fructose
•Examples: glycogen (stored energy), starch (potatoes), table sugar (sucrose), cellulose ( used in the cell wall of plants)
• Polymer: polysaccharide (many sugars)
Glucose C6H12O6

Lipids• Monomers: fatty acid chains linked by a glycerol
• Polymer: Lipids
Phospholipid
• Examples: Used in cell membranes, fat for insulation, waxes, oil, steroids (send messages), butter, and it stores energy

Proteins• Monomers: amino acid
• Polymer: proteins (amino acids joined by peptide bonds)
• Examples: enzymes (chemical processes), cell structures, muscle contractions, meat, beans, nuts
![Page 11: Agenda 1. Standards 2. Macromolecules Notes 3. HW: Macromolecules Booklet Warm-Up Question What do you know about carbohydrates, lipids and proteins?](https://reader035.fdocuments.net/reader035/viewer/2022062322/56649f3c5503460f94c5aa6e/html5/thumbnails/11.jpg)
Nucleic Acids• Monomer: nucleotide (phosphate, sugar, nitrogen base)
• Polymer: nucleic acids
• Examples: DNA and RNA (store cell information, assist in making proteins)
![Page 12: Agenda 1. Standards 2. Macromolecules Notes 3. HW: Macromolecules Booklet Warm-Up Question What do you know about carbohydrates, lipids and proteins?](https://reader035.fdocuments.net/reader035/viewer/2022062322/56649f3c5503460f94c5aa6e/html5/thumbnails/12.jpg)

Now you will create a book on these
macromolecules…• Title Page with your name• 4 pages should have
1. Title2. 3 sentences in your own words describing the macromolecule.3. Pictures of one unit.4. Pictures of items that contain these
macromolecules.
