Use of Cyclodextrin-Cholesterol Complex as a Primary Standard in Cholesterol Analysis
(Elsevier, 1993-06)
Cholesterol is an analyte commonly measured in various biological fluids. Enzymic procedures have virtually replaced the chemical methods for cholesterol determinations. Standardization of cholesterol assays often involve ...

(Wiley Periodicals, Inc.Oxford University Press, 2018-12-02)
2-(3-Pyrrolin-1-yl)-1,4-naphthoquinones: Photoactivated Alkylating Agents
(WILEY-VCH Verlag, 2008-09)
The preparation of 2-(3-pyrrolin-1-yl)-1,4-naphthoquinones and a study of their use as photoactivated alkylating agents is reported. The title compounds were easily synthesized by conjugate addition of the corresponding ...
Studies on the Biosynthesis of the Stephacidin and Notoamide Natural Products: A Stereochemical and Genetic Conundrum
(WILEY-VCH Verlag, 2011-04)
The stephacidin and notoamide natural products belong to a group of prenylated indole alkaloids containing a bicyclo[2.2.2]diazaoctane core. Biosynthetically, this bicyclic core is believed to be the product of an ...
Nuclear phosphoproteins : I. Isolation and characterization of a phosphoprotein fraction from calf thymus nuclei
(Elsevier, 1969-02-04)
A phosphoprotein fraction has been isolated from calf thymus nuclei which contains about 1.3% alkali-labile phosphorus by wt. The enzymatic reaction in which serine and threonine residues in the protein are phosphorylated ...
Molecular Design Approach Managing Molecular Orbital Superposition for High Efficiency without Color Shift in Thermally Activated Delayed Fluorescent Organic Lightâ Emitting Diodes
(Wiley Periodicals, Inc., 2019-02-01)
Molecular design principles of thermally activated delayed fluorescent (TADF) emitters having a high quantum efficiency and a color tuning capability was investigated by synthesizing three TADF emitters with donors at ...
The geologic role of polysulfides--Part II : The solubility of acanthite and covellite in sodium polysulfide solutions
(Elsevier, 1963-12)
The solubility of synthetic low-temperature silver sulfide (acanthite) in solutions of sodium polysulfide of different concentrations, different ratios of sulfur to sulfide and different acidity was determined. The solubility ...
Sculpting Metal‐binding Environments in De Novo Designed Three‐helix Bundles
(WILEY‐VCH Verlag, 2015-01)
De novo protein design is a biologically relevant approach used to study the active centers of native metalloproteins. In this review, we will first discuss the design process in achieving α3D, a de novo designed three‐helix ...
