  2. Polymers Is a large molecule that forms when smaller molecules are linked together by covalent bonds The smaller molecules that are joined together to form a polymer are called monomers Polymers can be classified as natural or synthetic.

  3. Synthetic Polymers Properties of a polymer depend on the type and number of monomers in the polymer. Rubber, nylon, and polyethylene are three examples of compounds that can be synthesized.

  4. Natural Polymers • Four types of polymers produced in plants and animal cells are starches, cellulose, nucleic acids and proteins. • Starches- made from glucose monomers • Sugars and polymers built from sugars are known as carbohydrates • Cellulose- main component of cotton and wood

  5. Natural Polymers (continued) • Nucleic Acids • Store information about structure and function • Large nitrogen-containing polymers found mainly in the nuclei of cells • There are two types DNA and RNA • Proteins • A polymer in which at least 100 amino acid monomers are linked through bonds between amino groups and carboxyl groups. • And amino acids is a compound that contains both carboxyl and amino functional groups in the same molecule.
