*THE CHEMISTRY OF LIFE…

1. Elements we need to recognize:

C = CarbonH = HydrogenO = OxygenN = Nitrogen

P = Phosphorus

Molecule: two or more atoms bonded togetherElement: matter made of only one type of atom

Bonds, bonds, bonds! Molecules are atoms bonded together. The bond stores energy. When that bond is broken, energy is released. More bonds = More energy!!

How do bonds form and break?

2. Chemical Reactions

Chemical reaction = the process by which atoms bond together or break apart.

A chemical bond occurs when two or more elements react together to form a chemical compound (molecule).

The compound is unique from its parent atoms.

Chemical equation: How scientists describe a chemical reaction.

Reactants: what goes IN to the chemical reaction, left side of arrow

Products: what is produced from the reaction, right side of arrow

3.MacromoleculesA. Macromolecules = large molecules made

from smaller molecules.

B.Polymer (many parts) macromolecule made up of many smaller, repeating molecules.

C.Monomer (one part) is a single unit which is bonded together to make polymers.

There are two types of reactions important to making monomers and polymers

1. Dehydration synthesis =

polymers are formed by removing water.

2.

Hydrolysis = breaking down polymers into monomers by the addition of H2O.

Hydro=water

Lysis=cut

4. Organic chemistry: the study of compounds that contain carbon atoms. (Life on earth is considered carbon based).

Organic = contains carbonInorganic = does NOT contain carbon

B. There are four types of organic

compounds found in living things… 1.

Carbohydrates

2. Lipids

3. Proteins

4. Nucleic Acids
