amino acid residue
The individual repeating units in a polypeptide chain or protein.
In IR spectroscopy, a type of vibration that generally produces a signal in the fingerprint region of an IR spectrum.
beta (b) pleated sheet
For proteins, a feature of secondary structure that forms when two or more protein chains line up side-by-side.
An alkane containing two rings that share two carbons
A thermodynamic cycle based on Hess’s law that relates the lattice energy of an ionic substance to its enthalpy of formation and to other measurable quantities. (Section 8.2)
A microcrystalline form of carbon. (Section 22.9)
Diamagnetic current in NMR
The circulation of electron density in a molecule in an applied magnetic fi eld.
Incorporation of a hetero atom into a solid to change its electrical properties. For example, incorporation of P into Si. (Section 12.7)
The use of electrolysis to reduce or refine metals. (Section 20.9)
