__**Terms used in Biochemistry**__ Structural isomers- differ in covalent partners. See example: pentane and 2-methyl butane. Geomeric isomers- differ in the arrangment of a double bond. If viewing a molecule and its Geometric isomer, one side of the will appear to have rotated or flipped on the double bond. Enantiomers- differ in arrangement of molecules around an asymmetric carbon. The Enantiomer of a molecule will appear as the mirror image of the molecule.
 * Biochemistry**- the study of the role of chemicals and chemical reactions in living organisms. Biochemistry includes the study of the molecular structure of different cellular components, including large molecules known as polymers.
 * Polymers**- large molecules consisting of smaller, repeating subunits(monomers). Carbohydrates, lipids, proteins and nucleic acids are all examples of polymers studied in biochemtistry.
 * Isomers-** this term is used to recognize variation in the structure of compounds that have the same number of atoms of each element. the greater number of atoms a molecule contains, the greater variety of isomers are possible.
 * Functional groups-** chemical groups that affect molecular function by being directly involved in chemical reactions.
 * Enzymes-** macromolecule composed of amino acids. Primary role: speeding up chemical reactions.
 * Hydrolysis-** this chemical reaction is used to break apart polymers. A water is broken up and the resulting hydrogen and hydroxyl replace the broken bond sites (which after the breaking of the bond would have charges)
 * Dehydration-** this chemical reaction is used to form polymers. A water is released so that each two polymers can join together.

 * Slideshow Overview of Biochemistry - (includes water, carbon, and functional groups)**

carbohydrates-** carboydrates play a big role in storing energy in the form of monomer chains made up of different monosaccharides.
 * __A look at polymers in detail__
 * lipids-** the main roles of lipid molecules are energy storage and structural components of cell membranes. Triglycerides, or fats, are a subgroup of lipids and is made up of a glycerol with three fatty acid chains attatched to it.
