Electrochemistry of methylated pterins :
(1982)
6,7-Dimethyl-5,6,7,8-tetrahydropterin (6,7-DMTHP) is an effective and widely used pseudo cofactor for phenylalanine hydroxylase in the hydroxylation reaction of phenylalanine. 6,7-DMTHP and other tetrahydropterins methylated ...
The stereochemistry and mechanism of the iron pentacarbonyl-promoted coupling of strained olefins to carbon monoxide :
(1985)
The stereochemistry and mechanism of the iron pentacarbonyl-induced coupling of strained olefins (e.g., 7-phenylnorbornadiene) to carbon monoxide is discussed. Emphasis is placed on determination of the structure of one ...
I. AN INVESTIGATION INTO THE NATURAL PRODUCTS CHEMISTRY OF THE SOFT CORAL ASTEROSPICULARIA RANDALLI. II. AN INVESTIGATION INTO THE NATURAL PRODUCTS CHEMISTRY OF THE NUDIBRANCH TRIDACHIA CRISPATA. III. STRUCTURE DETERMINATION OF THE 11BETA, 12BETA-EPOXYPUKALIDE FROM THE GORGONIAN LEPTOGORGIA SETACEA.
(1984)
Chapter 1 deals with the twenty-eight compounds which have been isolated from the soft coral Asterospicularia randalli, collected in May 1979 and April 1983 at Guam Island in the Pacific. Seven of the twenty-eight natural ...
I. OVERVIEW OF THE METHODOLOGY OF TRANSITION METAL SUBSTITUTION KINETICS. II. SPECTROPHOTOMETRIC INVESTIGATION OF THE EXTENT OF ION-PAIRING BETWEEN AQUOPENTAAMMINERHODIUM(III) AND CHLORIDE IN ACIDIC AQUEOUS SOLUTION. III. THE SYNTHESIS OF TRANS-DIAQUOBIS(ETHYLENEDIAMINE)IRIDIUM(III). IV. THE KINETICS OF THE ANATION BY CHLORIDE OF TRANS-DIAQUOBIS(ETHYLENEDIAMINE)RHODIUM(III) IN ACIDIC AQUEOUS SOLUTION.
(1980)
The work reported here is part of an effort to develop a new method for studying the kinetics of transition metal substitution reactions. In the past, reactions have been studied at high, constant ionic strength following ...
Development of methodology for the determination of catecholamines, indoleamines, and related hydroxylating enzymes.
(1980)
This study was concerned with the development and improvement of analytical procedures using liquid chromatography with electrochemical detection for the determination of activity of tyrosine hydroxylase, tryptophan ...
I. COMPARATIVE STUDY OF LIPIDS OF SHARK LIVERS. II. COMPARATIVE BIOCHEMICAL STUDY OF SOME GORGONIANS.
(1980)
Diterpenoid compounds, cetyl palmitate and hydrocarbons were examined from eggs of Pseudopterogorgia americana and five samples of Plexaura. Two diterpenoid compounds, mw 304 and 306, were obtained only from P. "REM" St. ...
Comparative temperature-dependent polarized Raman study of lithium potassium sulfate, sodium potassium sulfate, and the fast ion conductor lithium sodium sulfate.
(1981)
The temperature dependence of the external modes not containing any significant lithium ion contribution were also investigated in LiNaSO(, 4), LiKSO(, 4), and NaK(, 3)(SO(, 4))(, 2). Modes containing sulfate ion rotational ...
The thermodynamics of surfactant aggregation and adsorption at the clay-water inteface.
(1982)
Heats of adsorption indicated that at neutral pH anionic surfactants interact weakly with montmorillonite, but more strongly with alumina. The results also indicated that a calorimetric approach to studying surfactant-solid ...
Optimization of liquid chromatography with electrochemical detection of three micron reversed-phase column for neurochemical determinations /
(1984)
Liquid chromatography with electrochemical detection has become an established technique for the determination of catecholamines, indoleamines, and related enzymes. Previous work in this area has utilized lower efficiency ...
An investigation into the natural products chemistry of the sea hare Aplysia dactylomela.
(1980)
A diterpenoid alcohol, C(, 20)H(, 32)O(, 3), which was characterized as a novel isomer of the known diterpenoid dolatriol, was also isolated from the chloroform extract.
