Absolute confi guration
Which of the two possible isomers an enantiomer is (i.e., whether it is the right- or left-handed isomer).
The number of protons in the nucleus of an atom of an element. (Section 2.3)
The enthalpy change, ?H, required to break a particular bond when the substance is in the gas phase. (Section 8.8)
An electrode at which reduction occurs. (Section 20.3)
A means of protecting a metal against corrosion by making it the cathode in a voltaic cell. This can be achieved by attaching a more easily oxidized metal, which serves as an anode, to the metal to be protected. (Section 20.8)
Processes in which one or more substances are converted into other substances; also called chemical reactions. (Section 1.3)
A triplet of nucleotides on mRNA that directs incorporation of a specifi c amino acid into a polypeptide sequence.
complete ionic equation
A chemical equation in which dissolved strong electrolytes (such as dissolved ionic compounds) are written as separate ions. (Section 4.2)
The quantity of solute present in a given quantity of solvent or solution. (Section 4.5)
A reaction in which two smaller molecules combine to form a larger molecule. Water is invariably one of the products of such a reaction. (24.4)
free energy (Gibbs free energy, G)
A thermodynamic state function that gives a criterion for spontaneous change in terms of enthalpy and entropy: G = H - TS. (Section 19.5)
A catalyst that is in the same phase as the reactant substances. (Section 14.7)
Hückel criteria for aromaticity
To be aromatic, a monocyclic compound must have one 2p orbital on each atom of the ring, be planar or nearly so, and have (4n 1 2) p electrons in the cyclic arrangement of 2p orbitals
A nonpolar molecule derived from glycerol and fatty acids that is used by organisms for long-term energy storage. (Section 24.9)
Refers to groups occupying l,2-positions on a benzene ring.
Polymers made up of repeating urethane groups, also sometimes called carbamate groups (!N!CO2!).
The energy that an object possesses as a result of its composition or its position with respect to another object. (Section 5.1)
standard atomic weight
The weighted averages for each element, which takes into account isotopic abundance.
Tertiary structure of nucleic acids
The threedimensional arrangement of all atoms of a nucleic acid, commonly referred to as supercoiling
An internal salt of an amino acid; the carboxylate is negatively charged, and the ammonium group is positively charged
