• organic compound- Originally any compounds that were derived from nature, but the definition as now be changed to any Carbon Containing Compound because compounds derived from nature could be created sythetically.
  • inorganic cmpound- Compounds that did not come from a living thing
  • aromatic- any compound that contains a ring structure.
  • monosaccharides-simple sugars
  • isomers- Two or more compounds that have the same chemical formula, but have different structures. EX: Glucose & Frutose
  • amide group- When 2 amino acids combine by eliminating water between themselves, an H atom from the amino end and an OH atom from the acid end. (Le Couteur & Burreson 120)
  • peptide bond- The actual chemical bond between the carbon of one amino group and the nitrogen of another amino group (Le Couteur & Burreson 119)

  • Thermoset Material- material that is frozen in its shape forever (Le Couteur & Burreson 138)
  • Thermoplastic Material- opposite of thermoset material. it can be melted and remolded.(Le Couteur & Burreson 138)
  • Cis Double Bonds- when the 2 H atoms are on the same side as the double bond. resposible for the elasticity of rubber (Le Couteur & Burreson 145)
  • Trans Double Bonds- When the 2 H atoms are on different sides of the double bond. Responsible for the rigidness of rubber. (Le Couteur & Burreson 145)

  • Conjugation- Alternating double and single bonds. In dyes, it determines the wave length of visiable light that can be absobed  (Le Couteur & Burreson 166)
  • Antibiotic- Subtances of microbal origin that in very small amounts have antimicrobal activity.  (Le Couteur & Burreson 181-200)
  • Antimetabolic- A chemical that inhibits the growth of microbes. (Le Couteur & Burreson 181-200)
