Elements, Atoms, Molecules, Compounds

Molecule A group of atoms bonded together

Our Bodies are Made of Two Types of Molecules. . . Organic Molecules- giant chains of carbon AND hydrogen Inorganic Molecules- do not have both carbon and hydrogen These are what are bodies are made of, so it is also important that we are always trying to get them to maintain homeostasis We also use these molecules for energy!

Organic or Inorganic? Fat (C55H98 O6) Water (H2O) Carbon Dioxide (CO2) Write an I or an O next to each Fat (C55H98 O6) Water (H2O) Carbon Dioxide (CO2) Oxygen (O2) Sugar (C6H12O6) Protein (C2ONH2)x

We need these molecules to survive… How does our body obtain them?

Biomolecules “living” group of atoms Biomolecules are molecules produced by living organisms, including macromolecules

This unit is about biomolecules, but more specifically, it is about biological macromolecules

4 Macromolecules Carbohydrates Lipids (Fats) Proteins Nucleic Acids

What do these words mean? Micro MACRO

So what is a macromolecule? A macromolecule is a very large molecule made of many smaller units

“Mono” means…. Monogamy Monotonous

ONE MONO means

“Poly” means…. Polytheism Polygons Polygamy

MANY POLY means

Monomers and Polymers Monomers are the repetitive units of a polymer Polymers are long molecules built from repeating monomers

What is the monomer?

What is the monomer? ABCABCABCABCABCABC
