Basic Elements

99% of all living things are:

Sulfur (S)Carbon (C) Hydrogen (H)Nitrogen (N)Oxygen (O)Phosphorus (P)

Page 3: Biochemistry. Basic Elements 99% of all living things are: Sulfur (S) Carbon (C) Hydrogen (H) Nitrogen (N) Oxygen (O) Phosphorus (P)

Chemistry and Life

ORGANIC moleculesAnything that contains Carbon (C)Ex. Sugar (C6H12O6)

All Living Things (animals, plants, etc.)

INORGANIC moleculesDo NOT contain carbonEx. H2O, O2

Atmosphere, Rocks, Waste products

Page 4: Biochemistry. Basic Elements 99% of all living things are: Sulfur (S) Carbon (C) Hydrogen (H) Nitrogen (N) Oxygen (O) Phosphorus (P)

Acids and Bases

Measured as pHOn a scale from 1-14pH = a measure of the number of hydrogen atoms

Substances that are very acidic or very basic are dangerous to living things

Density

Amount of matter in any given space

Density = Mass / Volume

Solutions

Mixture of two or more substances

Solvent = does the dissolving (ex. Water)

Solute = is dissolved (ex. Salt)
