Thermodynamics of copper sulfides I. Heat capacity and thermodynamic properties of copper(I) sulfide, Cu2S, from 5 to 950 K
(Elsevier, 1987-11)
The heat capacity of Cu2S from 5 to 950 K was determined by adiabatic-shield calorimetry and the thermodynamic properties were evaluated. Transitions occur at 376 and about 710 K with [Delta]trsSm = (1.240+/-0.006)R and ...
Assay and properties of the enzyme catalyzing the biosynthesis of 1-O-alkyl dihydroxyacetone 3-phosphate
(Elsevier, 1981-10-01)
The properties of the enzyme alkyl dihydroxyacetone phosphate synthase (1-O-acyl dihydroxyacetone 3-phosphate + ROH --> 1-O-alkyl dihydroxyacetone 3-phosphate + fatty acid) in Ehrlich ascites tumor cell microsomes were ...
Are cationic [eta]3-allyl complexes general precursors to metallacyclobutanes? Synthesis and structure of [mu]-chloro-bis[([eta]3-allyl)-2,2'-bipyridyldicarbonylmolybdenum(II)] tetrafluoroborate
(Elsevier, 1984-08-28)
Silver tetrafluoroborate reacts with Cl(bipy)(CO)2([eta]3-C3H5)Mo in CH2Cl2 to give the dimeric cation, ([mu]-Cl)[(bipy)(CO)2([eta]3-C3H5)Mo]2+, isolated as the crystalline BF4- salt with CH2Cl2 of solvation (5). Complex ...
1,4-Additions of the highly functionalized copper reagents RCu(CN)ZnI [middle dot] 2 BFP3 to trisubstituted enones. A new BF3 promoted cyclization reaction
(Elsevier, 1988)
The new copper reagents RCu(CN)Zn I [middle dot] 2 BF3 1 containing various functional groups like esters, cyanides, chlorides or enoates react with [beta], [beta]'- disubstituted enones to afford the Michael adducts 4-7 ...
Calcium compartmentation in isolated renal tubules in suspension
(Elsevier, 1988-04)
Substantial increases of total cell Ca2+ have been observed in suspensions of isolated rabbit proximal tubules subjected to hypoxic injury or treated with exogenous ATP followed by apparent recovery with reoxygenation of ...
[omega]-1 and [omega]-2 hydroxylation of prostaglandins by rabbit hepatic microsomal cytochrome P-450 isozyme 6
(Elsevier, 1985-11-15)
Incubation of prostaglandin E1 (PGE1) with liver microsomes from control rabbits and from rabbits treated with ethanol or imidazole yielded 18-, 19-, and 20-hydroxy metabolites, representing hydroxylation at [omega]-2, ...
