Agenda 1. Standards2. Macromolecules Notes3. HW: Macromolecules Booklet

Warm-Up Question

• What do you know about carbohydrates, lipids and proteins?

The Chemistry of Life

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

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

Nucleic Acids• Monomer: nucleotide (phosphate, sugar, nitrogen base)

• Polymer: nucleic acids

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

What macromolecule applies to this picture?

A. Carbohydrate

B. Lipid

C. Protein

D. Nucleic Acid

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.

In class finish first 2 pages

Tonight - finish next 2 pages.

Tomorrow - finish last 2 pages.

Due at the next grading period.
