• Sit down and start to fill out the vocabulary organizer with any words that you know. This will be for homework.

Macromolecules

The Chemistry of Carbon

• Carbon is the element of life

• Able to bond to many different elements

• Bonds to other carbons to form very long carbon chains

Macromolecules

• “Giant Molecules”

• Macromolecules are made from thousands of smaller molecules combined

Macromolecules

• “Giant Molecules”

• Macromolecules are made from thousands of smaller molecules combined

• Monomer + monomer = polymer

• Monomer- single molecule

• Polymer- very large unit of molecules made by joining monomers together

• “Poly” = many• “Mono” = single

• Monomer- single molecule

• Polymer- very large unit of molecules made by joining monomers together

Macromolecules are polymers!!!!

Monomer Polymer

Monomer Polymer

Just one

Many joined together

4 Main Macromolecules

• Carbohydrates• Lipids• Nucleic Acids• Proteins

• Each of these are polymers made from linking smaller units together

PAUSE.

• What is a macromolecule?

• What do “mono” and “poly” mean?

• What is a monomer?

• What is a polymer?

Carbohydrates

• Compounds made of: carbon, hydrogen, and oxygen.

• Used for: Living things use carbohydrates as their main source of energy.

• Monomer: Monosaccharides

• Example: Sugars

Carbohydrates

• Compounds made of: carbon, hydrogen, and oxygen.

• Used for: Living things use carbohydrates as their main source of energy.

• Monomer: Monosaccharides

• Example: Sugars

• Monomer- Monosaccharide– “simple sugar”

• Monomer- Monosaccharide– “simple sugar”

• Polymer- Polysaccharide– “complex sugar”

• Starches are polysaccharides, or complex sugars, that animals use to store long term energy.

Lipids

• Compounds made from: Carbon, Hydrogen, Oxygen

• Used for: Energy storage, protective layers

• Made from: Fatty Acids

• Examples: Fats, Oils, Waxes, Steroids

• Lipids are not soluble in water

–Lipids do not dissolve in water

PAUSE.

• What do we use carbohydrates for ?

• What are the monomers of carbohydrates called?

• What are the monomers of Lipids called?

• What are lipids used for?

Nucleic Acid

• Compounds made from: Hydrogen, Carbon, Oxygen, Nitrogen, Phosphorus

• Used for: Store hereditary, or genetic information.

• Monomer: Nucleotides

• Example: DNA

Proteins

• Compounds made from: Carbon, Hydrogen, Oxygen, Nitrogen

• Used for: Chemical Reactions

• Monomer: Amino acids

• Example: Enzymes
