Chemistry of Life


polar - describes a molecule with opposite charges on opposite ends

non-polar - molecule that shares its electrons equally; does not have areas of charge

acid - compound that forms hydrogen ions (H+) in solution

base - compound that produces hydroxide ions (OH-) in solution

pH scale - measurement system used to indicate the concentration of hydrogen ions
(H+) in solution; ranges from 0 to 14

protein - macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed
by the body for growth and repair and to make up enzymes

carbohydrate - compound made up of carbon, hydrogen, and oxygen atoms; major
source of energy for the human body

lipid - large organic compounds made mostly of carbon and hydrogen with a small
amount of oxygen; examples are fats, oils, waxes, and steroids; are insoluble in water
and used by cells for energy storage, insulation, and protective coatings, such as in
membranes

nucleic acid - A polymer (polynucleotide) consisting of many nucleotide monomers;
serves as a blueprint for proteins and, through the actions of proteins, for all cellular
activities. The two types are DNA and RNA.

monomer - small molecular unit that is the building block of a larger molecule

polymer - large molecule formed when many smaller molecules bond together

enzyme - protein that acts as a biological catalyst

activation energy - the minimum amount of energy required to start a chemical reaction

adhesion - an attraction between molecules of different substances

cohesion - attraction between molecules of the same substance
