basic anhydride (basic oxide)
An oxide that forms a base when added to water; soluble metal oxides are basic anhydrides. (Section 22.5)
A nonplanar conformation of a cyclohexane ring in which carbons 1 and 4 of the ring are bent toward each other
Processes in which one or more substances are converted into other substances; also called chemical reactions. (Section 1.3)
A molecule composed of only two atoms. (Section 2.6)
A type of secondary structure of DNA molecules in which two anti parallel polynucleotide strands are coiled in a right-handed manner about the same axis
A negatively charged subatomic particle found outside the atomic nucleus; it is a part of all atoms. An electron has a mass 1>1836 times that of a proton. (Section 2.3)
energy of activation
In an energy diagram, the height of the energy barrier (the hump) between the reactants and the products.
Important biological molecules that catalyze virtually all cellular processes.
A way to view furanose and pyranose forms of monosaccharides. The ring is drawn fl at and most commonly viewed through its edge with the anomeric carbon on the right and the oxygen atom of the ring to the rear
An orbital that results from the mixing of different kinds of atomic orbitals on the same atom. For example, an sp3 hybrid results from the mixing, or hybridizing, of one s orbital and three p orbitals. (Section 9.5)
Any molecule or ion that can form a new covalent bond by donating a pair of electrons.
A common name for a thiol; that is, any compound that contains an -SH (sulfhydryl) group
Pauli exclusion principle
No more than two electrons may be present in an orbital. If two electrons are present, their spins must be paired
A conformation in which a hydrogen atom and a leaving group are approximately coplanar.
Matter that has a fixed composition and distinct properties. (Section 1.2)
A starting substance in a chemical reaction; it appears to the left of the arrow in a chemical equation. (Section 3.1)
sigma 1S2 molecular orbital
A molecular orbital that centers the electron density about an imaginary line passing through two nuclei. (Section 9.7)
Compounds containing silicon and oxygen, structurally based on SiO4 tetrahedra. (Section 22.10)
An excellent leaving group (OTs). transition state (Sect. 6.6): A state through which a reaction passes. On an energy diagram, a transition state corresponds with a local maximum.
A triester formed from glycerol and three long-chain carboxylic acids.
