Hormones that are secreted by the cortex (the outer layer) of the adrenal glands. Adrenocortical hormones are typically characterized by a carbonyl group or hydroxyl group at C11 of the steroid skeleton.
An amine in which the nitrogen atom is connected directly to an aromatic ring.
Compounds with the same molecular formula but a different connectivity of their atoms
A region of a polymer inwhich the chains are linearly extended and closein proximity to one another, resulting in van der Waals forces that hold the chains close together.
Enthalpy change, DH
The difference in total bond strengths and solvation between various points under comparison on a reaction coordinate diagram
For cyclohexane, the steric interactions that occur between the flagpole hydrogen atoms in a boat conformation.
The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) that participate in a reaction.
A fi ve-membered cyclic form of a monosaccharide.
A reaction in which an amino group is treated with excess methyl iodide, thereby converting it into an excellent leaving group, followed by treatment with a strong base to give an E2 reaction that yields an alkene.
Solids that are composed of ions. (Section 12.1)
A type of isomerism involving keto (from ketone) and enol tautomers
Theresonance-stabilized intermediate of a nucleophilicaromatic substitution reaction.
Molecules with low molecular weights, which can be joined together (polymerized) to form a polymer. (Section 12.8)
A compound that does not rotate plane-polarized light.
A device that uses strong magnetic and electrostatic fields to accelerate charged particles. (Section 21.3)
Compounds that are very similar in structure to triglycerides, with the main difference being that one of the three fatty acid residues is replaced by a phosphoester group.
A term used to designate the configuration of a chirality center, determined in the following way: Each of the four groups is assigned a priority, and the molecule is then rotated (if necessary) so that the #4 group is directed behind the page (on a dash). A counterclockwise sequence for 1-2-3 is designated as S.
tertiary alkyl halide
An organohalide in which the alpha (a) position is connected to three alkyl groups.
The angle between two groups in a Newman projection, also called the dihedral angle.
Valence Shell Electron Pair Repulsion theory, which can be used to predict the geometry around an atom.
