Compounds that will react with either acids or bases. Amino acids are amphoteric.
The electrode at which oxidation occurs. (18.2)
A reaction in which a ketone is treated with a peroxy acid and is converted into an ester via the insertion of an oxygen atom.
The ability of the atoms of an element to form bonds with one another. (22.3)
A positively charged ion. (Section 2.7)
A region of a polymer inwhich the chains are linearly extended and closein proximity to one another, resulting in van der Waals forces that hold the chains close together.
Any substituent on a benzene ring that causes the rate of electrophilic aromatic substitution to be lower than that for benzene.
A covalent bond involving two electron pairs. (Section 8.3)
Stereoisomers that are nonsuperposable mirror images of each other; refers to a relationship between pairs of objects
Gibbs free energy
A thermodynamic state function that combines enthalpy and entropy, in the form G = H - TS. For a change occurring at constant temperature and pressure, the change in free energy is ?G = ?H - T?S. (Section 19.5)
Gibbs free energy change (DG°)
The energy that dictates the position of chemical equilibria and rates of chemical reactions. A thermodynamic function of enthalpy, entropy, and temperature, given by the equation DG° 5 DH° 2 TDS°. If DG° , 0, the position of equilibria for the reaction favors products. If DG° . 0, the position of equilibria favors reactants.
A back-to-back arrangement of phospholipid monolayers, often forming a closed vesicle or membrane.
A compound in which one or more OH groups, and possibly additional oxygen atoms, are bonded to a central atom. (Section 16.10)
A polyatomic anion that contains one or more oxygen atoms. (Section 2.8)
A six-membered cyclic hemiacetal form of a carbohydrate.
An equation thatdescribes the relationship between the rate of a reactionand the concentration of reactants.
The sloweststep in a multistep reaction which determines the rate of the reaction.
A solution prepared by dissolving Ag2O in aqueous ammonia; used for selective oxidation of an aldehyde to a carboxylic acid.
A hydrocarbon containing one or more carbon-carbon double or triple bonds. The three classes of unsaturated hydrocarbons are alkenes, alkynes, and arenes
A net neutral compound that exhibits charge separation. Amino acids exist as zwitterions at physiological pH.
