HW Macromolecules Booklet

• Warm-Up Question
• What do you know about carbohydrates, lipids and
  proteins?

2
The Chemistry of Life
3
Which atoms are found in all living things?
CHNOPS C carbon H hydrogen N nitrogen O
oxygen P phosphorus S sulfur
4
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)

5
Molecules

• many atoms -gt molecules

• many molecules -gt macromolecules
• macro large
• molecule atoms that hook up

6
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.

7
4 types of polymers or macromolecules or organic
compounds

• Carbohydrates (sugar)
• Lipids (fat)
• Protein
• Nucleic Acids

8
Carbohydrates

• Monomer
• monosaccharide (one sugar)
• Examples
• glucose and fructose

• Polymer
• polysaccharide (many sugars)

• Examples
• glycogen (stored energy), starch (potatoes),
  table sugar (sucrose), cellulose ( used in the
  cell wall of plants)

9
Lipids

• Monomers
• fatty acid chains linked by a glycerol
• Polymer
• Lipids

• Examples
• Used in cell membranes, fat for insulation,
  waxes, oil, steroids (send messages), butter, and
  it stores energy

10
Proteins

• Monomers
• amino acid
• Polymer
• proteins
• (amino acids joined by peptide bonds)

• Examples
• enzymes (chemical processes), cell structures,
  muscle contractions, meat, beans, nuts

11
Nucleic Acids

• Examples
• DNA and RNA
• (store cell information, assist in making
  proteins)

• Monomer
• nucleotide
• (phosphate, sugar, nitrogen base)
• Polymer
• nucleic acids

12
What macromolecule applies to this picture?

• A. Carbohydrate
• B. Lipid
• C. Protein
• D. Nucleic Acid

13
Now you will create a book on these
macromolecules

• Title Page with your name
• 4 pages should have
• 1. Title
• 2. 3 sentences in your own words describing
  the macromolecule.
• 3. Pictures of one unit.
• 4. Pictures of items that contain these
• macromolecules.

14
In class finish first 2 pages

• Tonight - finish next 2 pages.
• Tomorrow - finish last 2 pages.
• Due at the next grading period.
