1.
Amino Acid: 
The monomer/building block for proteins.
2.
Biomolecule: A molecule found in living things.
3.
Carbohydrate: Biomolecule that includes sugar, starch, or cellulose and it serves as a major energy source in the diet of animals. These compounds contain only CARBON, HYDROGEN, and OXYGEN, usually in the ratio 1:2:1.
4.
Carbohydrates: 
Potato, Rice, Bread, and Sugar are all examples of foods rich in which contain many __.
5.
Cell membrane: 
The phospholipid bilayer that forms the outer boundary of the cell
6.
Dehydration Synthesis: A chemical reaction in which two molecules are bonded together with the REMOVAL of a water molecule.
7.
Disaccharide: 
A molecule formed by joining TWO monosaccharides through a dehydration synthesis;
Ex. Sucrose (table sugar), and Lactose.
8.
Energy: One of the functions of lipids is to store ____.
9.
Enzyme: 
A specialized protein that catalyzes (speeds up) the chemical reactions of a cell.
10.
Fatty acid: The basic component (monomer) of MOST lipids. It is composed of a chain of carbon and hydrogens attached to a carboxylic acid.
11.
Glucose: 
A carbohydrate (C₆H₁₂O₆) produced by photosynthesis. It is the form of sugar that circulates in the blood and is used by the body to make energy.

12.
Hydrophillic: "Water-loving"; describes polar molecules (or parts of molecules) that dissolve in water.
13.
Hydrophobic: "Water-fearing"; describes nonpolar molecules (or parts of molecules) that do not dissolve in water.
14.
Lipid: Biomolecule made mainly from chains of carbon and hydrogen atoms, which gives it NONPOLAR qualities.
This includes fats, oils, and waxes.
15.
Macromolecule: A very LARGE organic molecule, usually a polymer.

Monosaccharide: The building block of a carbohydrate; a single sugar.
Ex. Glucose, Ribose
18.
Organic: A word used to describe a molecule that contains the element Carbon.
19.
Phospholipid: 
A lipid made of a phosphate group and two fatty acids; Consists of a hydrophilic polar head and two hydrophobic non-polar tails; forms cell membranes.
