Freezing front motion and heat transfer outside an infinite, isothermal cylinder
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1965-09)
A numerical method is developed for calculation of the temperature field in a material that freezes outside an isothermal cylinder. Numerical values are presented for the freezing front location and for the rate of heat ...
2,3,5-Triphenyl-2H-tetrazolium chloride as a reagent for the determination of sugar mixtures by a differential reaction-rate technique
(Elsevier, 1965-01)
The rates of reaction of 2,3,5-triphenyl-2H-tetrazolium chloride with the more common hexoses (glucose, fructose, mannose, sorbose and galactose) and pentoses (xylose and ribose) have been studied. Under certain conditions, ...
Distribution of [alpha]-aminoisobutyric-C14 acid in rats deficient in thiamine, pantothenate, fatty acids, or potassium
(Elsevier, 1965-08)
A nutritional deficiency of fatty acids in young rats resulted in a marked elevation of the steady-state serum level of an injected dose of [alpha]-aminoisobutyric acid, and in a decrease in the transport of this model ...
Glutamine synthetase : VI. Mechanism of the dithiol-dependent inhibition by arsenite
(Elsevier, 1965-01)
Dithiol-dependent inhibition by arsenite has been demonstrated in glutamine synthetase (-glutamate: ammonia ligase (ADP), EC 6.3.1.2) obtained from various sources: from Neurospora to mammalian tissues. With a partially ...
The effect of metabolic inhibitors on transport and exchange of amino acids in Ehrlich ascites cells
(Elsevier, 1965-09-27)
1. 1. Cyanide and 2-deoxyglucose inhibit transport fluxes but do not inhibit exchange fluxes of amino acids in Ehrlich ascites cells. This is true whether the exchange flux is of the same order of magnitude as the transport ...
Enrichment of proteins with amino acid residues, employing p, p'-difluoro-m, m'-dinitrodiphenyl sulfone,
(Elsevier, 1965-04)
The bifunctional reagent, p, p'-difluoro-m,m'-dinitrodiphenyl sulfone, was employed to conjugate a variety of amino acids to the protein, gelatin. Among the amino acids tried, tyrosine conjugated most readily. The tyrosyl ...
Metabolism of plasmalogen III. Relative reactivities of acyl and alkenyl derivatives of glycerol-3-phosphorylcholine
(Elsevier, 1965-06-01)
1. (1) The alkenyl ether derivatives of phospholipids (plasmalogens) react at slower rates than the acyl analogs in several enzyme-catalyzed reactions.2. (2) Alkenylglycerol-3-phosphorylcholine is essentially inert as a ...
Succinate oxidation by human liver mitochondria
(Elsevier, 1965-09)
Factors controlling the rate of oxidation of succinate were studied in mitochondria isolated from twenty-seven specimens of normal human liver obtained at operation. These were compared with mitochondria prepared from the ...
Polarographic reduction of hydrogen ion in non-aqueous solvents
(Elsevier, 1965-12)
The polarographic reduction of hydrogen ion, furnished by dissociation of a Bronsted acid or present in the undissociated Bronsted acid, is reviewed for the situation where a solvent other than water is involved.
