A functional group characterized by two alkoxy (OR) groups connected to the same carbon atom.Acetals can be used as protecting groups for aldehydes or ketones.
A format for naming amines containing simple alkyl groups.
A solution in which the solvent is water. (4.1)
Delocalized electrons move freely through “bands” formed by overlapping molecular orbitals. (21.3)
Center of symmetry
A point so situated that identical components of an object are located on opposite sides and equidistant from that point along any axis passing through it.
A compound containing two adjacent p bonds.
A molecule containing two amino acid units joined by a peptide bond
A conformation about a carboncarbon single bond in which the atoms or groups on one carbon are as close as possible to the atoms or groups on an adjacent carbon.
The negative charge carried by an electron; it has a magnitude of 1.602 * 10-19 C. (Section 2.3)
electrospray ionization (ESI):
In mass spectrometry, an ionization technique in which the compound is first dissolved in a solvent and then sprayed via a high-voltage needle into a vacuum chamber. The tiny droplets of solution become charged by the needle, and subsequent evaporation forms gas-phase molecular ions that typically carry one or more charges.
A compound containing a hydroxyl group bonded to a doubly bonded carbon atom.
The number of times per second that one complete wavelength passes a given point. (Section 6.1)
A hypothetical gas whose pressure, volume, and temperature behavior is completely described by the ideal-gas equation. (Section 10.4)
A nucleoside in which a molecule of phosphoric acid is esterifi ed with an !OH of the monosaccharide, most commonly either the 39!OH or the 59!OH.
During the polymerization process, compounds constructed from just a few monomers.
Polyunsaturated fatty acid
A fatty acid with two or more carbon-carbon double bonds in its hydrocarbon chain
The separation of enantiomers from a mixture containing both enantiomers.
Matter that has both a definite shape and a definite volume. (Section 1.2)
A reaction that obeys conservation of orbital symmetry.
A process that involves the removal of a carbon atom from an aldose. The aldehyde group is first converted to a cyanohydrin, followed by loss of HCN in the presence of a base.
