BIOL 1106Professor T. NeelyLab #2 – Molecular Models1
2IntroductionAtomsare the smallest unit of matter. When two or more atomsbond, amoleculeis formed. The result of the bonding betweenatoms of two or more different elements is acompound.Of all the elements, carbon is of special importance because itenables the diversity we see in life. Compounds which containcarbon areorganic compounds, while those compounds that donot contain carbon are referred to asinorganic compounds.The different properties which organic compounds have aredetermined by thefunctional groupswhich they contain.Functional groups give organic compounds their unique properties.The following are some examples of functional groups:Amino group (NH2), Carboxyl group (COOH), Hydroxyl group (OH)and Carbonyl group (CO).
Functional Groups3Functional groupsare groups of atoms that like to bond withmolecules that contain carbon (organic molecules).Without thesefunctional groups, organic molecules would not really have anyunique function or properties (they would just be hydrocarbons:molecules just made up of hydrogen and carbon).We know that this is a train, however, without the engine, we don’tknow what type of train this is. . . steam, electric, diesel?
Functional Groups4But with the engine on it, we know that this is a steam train!. . . .that is what functional groups do for organic molecules;they give them their unique properties.Organic moleculeFunctional group
Amino Group – NH25Anamino groupis made up of one Nitrogen atom and two Hydrogenatoms.Amino groups are found in organic compounds calledAminessuch as amino acids (it’s the “amino” part of the amino acid).HHN
Carboxyl Group – COOH6Acarboxyl groupis made up of one Carbon atom, two Oxygen atoms,and one Hydrogen atom.Carboxyl groups are found incarboxylic acidssuch as amino acids (it’s the “acid” part of the amino acid.HCOODouble bondC
Hydroxyl Group – OH7Ahydroxyl groupis made up of one Oxygen atom, and one Hydrogenatom.Hydroxyl groups are found inalcohols and sugarssuch as glucose.
