1. Polymers - Summary A polymer is a large molecule formed by the covalent bonding of repeating smaller molecules. The smaller molecules that combine to form a polymer are called monomers. 23.4

2. Polymers Summary Two Types of Polymers Addition Polymers - An addition polymer forms when unsaturated monomers react to form a polymer Condensation Polymers - Condensation polymers are formed by the head-to-tail joining of monomer units. 23.4

11. Protein Summary Amino acid is any compound that contains an amino group (-NH 2 ) and a carboxyl group (-COOH) A peptide is any combination of amino acids (2 or more) where the amino group of one amino acid combined with the carboxyl group of another. Amino Acid + Amino Acid = Peptide Protein is a peptide with more than 100 amino acids
