  1. 3. an unsaturated hydrocarbon that contains at least one benzene structure
  2. 7. a solution that contains less than the maximum amount of solute that it could hold at a given temperature
  3. 8. a simple molecule that can link with other monomers to form large molecules called polymers. For example, glucose monomers combine to form the polymer starch
  4. 11. a hydrocarbon in which at least one of the hydrogen atoms has been replaced with another atoms or group of atoms. The replacement atom or group of atoms is called a functional group.
  5. 13. the nucleic acid responsible for most cellular reproduction, growth, and developement; abbreviation for deoxyribonucleic acid
  6. 15. a class of organic compounds that serve as the building blocks of proteins
  7. 16. a substituted hydrocarbonin which a hydroxyl groupn (OH) replaces a hydrogen atom
  8. 18. a substituted hydrocarbon in which a pair of hydrogen atoms bonded to a carbon atom other than those at the end of the carbon chain are replaced by an oxygen atom, forming a carbonyl group (C = O)
  9. 19. any of a group of biochemical molecules that act as the monomers to make nucleic acids. Each consists of sugar, a nitrogen base, and a phosphate group.
  10. 21. a biochemical polymer that encodes, stores, and provides instructions for cellular processes

  1. 1. an atom or group of atoms that replaces a hydrogen atom to form a substituted hydrocarbon;also called a substituent
  2. 2. a hydrocarbon that has only single bonds between its carbon atoms
  3. 4. a six-carbon unsaturated hydrocarbon ring with the electrons from the C-C bonds equally distributed among the carbon atoms. It is the key feature in aromatic hydrocarbons.
  4. 5. an organic compound comprised of carbon, hydrogen, and oxygen atoms that is the basic energy source for living organisms; includes sugars and starches
  5. 6. any group of compounds that have the same molecular formula but different structures
  6. 9. a large molecule formed by linking smaller molecules, called monomers. For example, nucleic acid, a polymer, is formed by linking nucleotide monomers
  7. 10. a biochemical polymer made of amino acids. Proteins are the building blocks for muscle, blood, skin, and hair in humans and animals.
  8. 12. a covalenty bonded compound containing carbon
  9. 14. a substituted hydrocarbon in which the replacement by an oxygen atom of a pair of hydrogen atoms at the end of a hydrocarbon chain forms a carbonyl group (C = O)
  10. 17. an organic compound consisting of only hydrogen and carbon atoms
  11. 20. organic compounds that provide long-term energy storage in living organisms; includes fats, oils, waxes, and steroids
