 * Proteins are two or more polypeptides linked together in one massive molecule.
 * Polypeptides are amino acids linked together.
 * The amino acids are bonded by peptide bonds
 * All amino acids have a carboxyl(ionized) and amino group within their structure

 * Antibodies- proteins that protect the body from germs
 * Enzymes- proteins that speed up chemical reactions
 * DNA and RNA - genetic make up and can be passed on to offspring
