Chemical Basis of Life
Mixture 2 or more elements or compounds mixed but not chemically combined. –Ex- air, soil, salad
Solution (p 42) A mixture in which one or more substances are uniformly spread out in another substance. –Ex-sugar water, salt water
2 parts to a solution Solvent- –does the dissolving (water) Solute- –gets dissolved (salt, sugar)
Acids/Bases pH Scale- (p 44) 1-14 7 = neutral 1-6 = acid 8-14 = basic (alkaline)
Acids Release hydrogen ions (H+) into a solution. –Ex- hydrochloric acid, –HCl H+ + Cl-
Bases Release hydroxide ions (OH-) into a solution. –Ex. sodium hydroxide –NaOH Na+ + OH-
Inorganic Compounds Do not contain carbon. –Ex. salt, water, calcium phosphate
Organic Compounds Carbon containing compounds –Ex. carbohydrates, proteins, lipids –Contain- C, H, O, N
Polymerization Process of putting together many smaller compounds to make large compounds
Monomers Small compounds that are put together
Polymer Complex molecule that results

Chemical Bonds and Reactions. Two kinds of bonds Ionic Covalent Chemical Bonds and Reactions.
Elements and Compounds. What is an element? A pure substance composed of the same type of atom throughout. Cannot be broken down into simpler substances.
Chapter 6.1 Biochemistry. Atoms Atoms: The building blocks of matter and the smallest particle of an element that exhibits characteristics of that element.
Acids and Bases PS-3.8 Classify various solutions as acids or bases according to their physical properties, chemical properties (including neutralization.
Water Why is water so important to life? Water covers more than 75% of the Earth’s surface. Living organisms are composed of 60-90% water. Life.
Biochemistry. Basic Elements 99% of all living things are: Sulfur (S) Carbon (C) Hydrogen (H) Nitrogen (N) Oxygen (O) Phosphorus (P)
A mixture is a material composed of 2 or more elements or compounds that are physically mixed together but not chemically Example: salt & pepper.
