The difference in Gibbs free energy between reactants and a transition state
alpha (a) helix
For proteins, a feature of secondary structure that forms when a portion of the protein twists into a spiral.
A high-energy intermediate formed during the elimination-addition reaction that occurs between chlorobenzene and either NaOH (at high temperature) or NaNH2.
Bonding molecular orbital
A molecular orbital in which electrons have a lower energy than they would in isolated atomic orbitals
A proton donor
A step in a chain reaction characterized by the reaction of a reactive intermediate and a molecule to give a new reactive intermediate and a new molecule.
The species formed when an acid transfers a proton to a base
A unimolecular elimination reaction.
A class of lipids which includes leukotrienes, prostaglandins, thromboxanes, and prostacyclins.
A property of the electron that makes it behave as though it were a tiny magnet. The electron behaves as if it were spinning on its axis; electron spin is quantized. (Section 6.7)
A compound containing two hydroxyl groups (OH) connected to the same carbon atom.
A reaction with water. When a cation or anion reacts with water, it changes the pH. (Sections 16.9 and 24.4)
A representation of covalent bonding in a molecule that is drawn using Lewis symbols. Shared electron pairs are shown as lines, and unshared electron pairs are shown as pairs of dots. Only the valence-shell electrons are shown. (Section 8.3)
An equation that relates the cell emf, E, to the standard emf, E°, and the reaction quotient, Q: E = E° - 1RT>nF2 ln Q. (Section 20.6)
Polymers of high molecular weight that carry genetic information and control protein synthesis. (Section 24.10)
A group that directs the regiochemistry of an electrophilic aromatic substitution reaction such that the incoming electrophile is installed at the ortho or para positions.
The name given to O3, an allotrope of oxygen. (Section 7.8)
A characteristic that gives a sample of matter its unique identity. (Section 1.1)
A measure of the energy absorbed from radiation by tissue or other biological material; 1 rad = transfer of 1 * 10-2 J of energy per kilogram of material. (Section 21.9)
A detailed picture, or model, of how the reaction occurs; that is, the order in which bonds are broken and formed and the changes in relative positions of the atoms as the reaction proceeds. (Section 14.6)
