A type of secondary structure in which a section of polypeptide chain coils into a spiral, most commonly a right-handed spiral.
In SN2 reactions, the side opposite the leaving group, which is where the nucleophile attacks.
The dipole moment that is due to unequal electron sharing between two atoms in a covalent bond. (Section 9.3)
The enthalpy change required to break a bond in a mole of gaseous molecules. (9.10)
C-Terminal amino acid
The amino acid at the end of a polypeptide chain having the free !COOH group.
chemical shift (d)
In an NMR spectrum, the location of a signal, defined relative to the frequency of absorption of a reference compound, tetramethylsilane (TMS).
A drawing style in which none of the bonds are drawn. Groups of atoms are clustered together when possible. For example, isopropanol has two CH3 groups, both of which are connected to the central carbon atom, shown like this: (CH3)2CHOH.
Compounds that have the same molecular formula but differ in the way the atoms are connected.
elimination (of radicals)
In radical reaction mechanisms, a step in which a bond forms between the alpha (a) and beta (b) positions. As a result, a single bond at the b position is cleaved, causing the compound to fragment into two pieces.
A protein molecule that acts to catalyze specific biochemical reactions. (Section 14.7)
A voltaic cell that utilizes the oxidation of a conventional fuel, such as H2 or CH4, in the cell reaction. (Section 20.7)
gas constant (R)
The constant of proportionality in the ideal-gas equation. (Section 10.4)
When orbitals of equal energy are available but there are not enough electrons to fi ll all of them completely, one electron is put in each before a second electron is added to any
A substance that exhibits one or more partially ordered liquid phases above the melting point of the solid form. By contrast, in nonliquid crystalline substances the liquid phase that forms upon melting is completely unordered. (Section 11.7)
A reaction in which an acid and a base react in stoichiometrically equivalent amounts; the neutralization reaction between an acid and a metal hydroxide produces water and a salt. (Section 4.3)
Cleavage by light.
Light for which all photons have the same polarization, generally formed by passing light through a polarizing filter.
specific heat 1Cs2
The heat capacity of 1 g of a substance; the heat required to raise the temperature of 1 g of a substance by 1 °C. (Section 5.5)
In IR spectroscopy, atype of vibration that generally produces a signal in the diagnostic region of an IR spectrum.
A reaction that obeys conservation of orbital symmetry.
