activation energy (Ea).
The minimum amount of energy required to initiate a chemical reaction. (13.4)
A monosaccharide containing an aldehyde group
The energy gap between a fully occupied band called a valence band and an empty band called the conduction band. (Section 12.7)
A structural form of protein in which two strands of amino acids are hydrogen-bonded together in a zipperlike configuration. (Section 24.7)
A ligand in which two linked coordinating atoms are bound to a metal. (Section 23.3)
A proton acceptor
A chemical reaction in which two or more substances combine to form a single product. (Section 3.2)
An ordered crystalline region in the solid state of a polymer. Also called a crystallite.
A class of lipids which includes leukotrienes, prostaglandins, thromboxanes, and prostacyclins.
For a mixture containing two enantiomers, the difference between the percent concentration of the major enantiomer and the percent concentration of its mirror image.
The unit in which frequency is measured: s 21 (read “per second”).
Heterolytic bond cleavage
Cleavage of a bond so that one fragment retains both electrons and the other retains none.
The sum of the number of protons and neutrons in the nucleus of a particular atom. (Section 2.3)
The number of grams of solute in each 100 g of solution. (Section 13.4)
metallic elements (metals)

A type of carbocation rearrangement in which a methyl group migrates.
retention of configuration
During a reaction, when the configuration of a chirality center remains unchanged.
Experimental conditions that permit the establishment of equilibrium between two or more products of a reaction. The composition of the product mixture is determined by the relative stabilities of the products.
