An organic compound containing the hydroxyl group —OH. (24.4)
Compounds containing a carbon-carbon triple bond.
The rules used in naming substances. (Section 2.8)
The spreading of one substance through a space occupied by one or more other substances. (Section 10.8)
The attraction between the positive end of one dipole and the negative end of another.
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.
Proteins that consist of linear chains that are bundled together.
A solution that obeys Raoult’s law. (Section 13.5)
isoelectric point (pI)
For an amino acid, the specific pH at which the concentration of the zwitterionic form reaches its maximum value.
law of definite proportions
A law that states that the elemental composition of a pure substance is always the same, regardless of its source; also called the law of constant composition. (Section 1.2)
A compound capable offunctioning as an electron pair acceptor.
A system of measurement used in science and in most countries. The meter and the gram are examples of metric units. (Section 1.4)
The product obtained when a monosaccharide is treated with an amine in the presence of an acid catalyst.
Nucleophilic aromatic substitution
A reaction in which a nucleophile, most commonly a halogen, on an aromatic ring is replaced by another nucleophile.
The specifi c rotation of a mixture of enantiomers divided by the specifi c rotation of the enantiomerically pure substance (expressed as a percent). Optical purity is numerically equal to enantiomeric excess, but experimentally determined.
The pH of blood (approximately 7.3).
polar aprotic solvent
A solvent that lacks hydrogen atoms connected directly to an electronegative atom.
Reversibly creating an unreactive group for the purpose of preventing a functional group from potentially reacting to give an unwanted product or products
A region of space around a nucleus that can be occupied by electrons, corresponding to a principal quantum number
Lipids that are based on a tetracyclic ring system involving three six-membered rings and one five-membered ring. Cholesterol is an example.
