Preparation of halomethaneboronates
(Elsevier, 1982-08-10)
A facile preparation of iodomethaneboronic esters is described. The key step utilizes a tin hydride reduction of dichloromethaneboronic esters.
An electrochemical ketal synthesis from 2-carboxy-2-allyl-tetrahydropyrans
(Elsevier, 1982)
2-Substituted tetrahydropyranyl-2-carboxylates have been converted to mixed ketals by electrochemical oxidative decarboxylation.
Molecular mobilities and the lowered osmolality of the chromaffin granule aqueous phase
(Elsevier, 1982-09-13)
Carbon-13 spin-lattice relaxation times, T1, have been measured in whole adrenal medullary tissue slices, in suspensions of isolated chromaffin granules, in the reconcentrated chromaffin granule lysate, and in various model ...
Stereospecific synthesis and enzyme studies of CDP-diacylglycerols
(Elsevier, 1982-09-14)
The fatty acid specificity of two enzymes that metabolize CDPdiacylglycerol, CDPdiacylglycerol hydrolase (EC 3.6.1.26) and CDPdiacylglycerol:inositol phosphatidyltransferase (EC 2.7.8.11), has been examined in guinea pig ...
Ability of growth hormone fragments to compete with 125I-iodinated human growth hormone for specific binding to isolated adipocytes of hypophysectomized rats
(Elsevier, 1982-12-30)
Several noncovalent complexes of large fragments of human GH, which are less active than native human GH in stimulating glucose metabolism in adipose tissue of hypophysectomized rats, were tested for their ability to compete ...
The stereochemistry of the oxidative dehydrogenation of allyl alcohol-3-d1 over a silver catalyst
(Elsevier, 1982-06)
The stereochemistry of the oxidative dehydrogenation of (Z)-allyl alcohol-3-d1 to acrolein over a silver catalyst has been studied using microwave spectroscopy for analyses. With oxygen present randomization was less than ...
524--NAD/NADH as a model redox system: Mechanism, mediation, modification by the environment
(Elsevier, 1982-07)
The biologically important redox couple, [beta]-nicotinamide adenine dinucleotide/1,4,[beta]-dihydronicotinamide adenine dinucleotide, provides a grossly reversible prototype system for an overall electrode reaction ...
Equilibrium swelling of pigment gallstones: Evidence for network polymer structure
(Wiley Subscription Services, Inc., A Wiley Company, 1982-03)
A major component of pigment gallstones (PS) is a black, insoluble substance. It has been suggested that this pigment material might be a highly crosslinked polymer, and if such were the case, it should imbibe solvent ...
