Erythrocyte metabolism and function: Hexokinase inhibition by 2,3-diphosphoglycerate and interaction with ATP and Mg2+
(Elsevier, 1969-11-18)
Recent findings have suggested an important role for variation in levels of 2,3-diphosphoglycerate and ATP in the regulation of oxygen transport by the human erythrocyte, and in making homeostatic adjustments to hypoxia. ...
Protein-carbohydrate interaction : VIII. A turbidimetric method for the analysis of -mannose
(Elsevier, 1967-08)
A unique, spectrophotometric method for the quantitative of -mannose in the presence of other sugars is described. The procedure depends on the degree to which the turbidity formed on interaction of concanavalin A with ...
The inhibition of purine biosynthesis De novo in Bacillus subtilis by cordycepin
(Elsevier, 1964-04-27)
1. 1. Cordycepin has been shown to inhibit purine biosynthesis de novo as evidenced by a decreased incorporation of radioactive formate into the nucleic acid purines of Bacillus subtilis.2. 2. The incorporation of radioactive ...
The polarography of aqueous pertechnetate ion
(Elsevier, 1967)
The polarographic reduction of pertechnetate in 4-0.01 M perchloric acid media takes place in two stages. The E of the more positive wave at +0.10 to -0.17 V S.C.E. is pH-dependent, E=0.06-0.106 pH. Coulometry indicates a ...

Determination of small amounts of zirconium--II : Analysis of refractory samples
(Elsevier, 1963-08)
In connection with the determination of small amounts of zirconium in complex samples, procedures have been developed for bringing various types of sample into solution and removing possible interferences, which procedures ...
Transport of amino acids in ehrlich ascites cells: Competitive stimulation
(Elsevier, 1967-09-09)
1. 1. The term `competitive stimulation' refers to an experimental finding in which the uptake of one amino acid is increased in the presence of another amino acid when both are initially present extracellularly. The uptake ...
The acid strength of the amino group as a factor in the transport of amino acids
(Elsevier, 1963)
1. 1. Halogen atoms have been introduced on the [beta]-carbons of amino acids in order to dissociate effects on pKa of the amino group on transport, from effects of the hydrophilic or hydrophobic character of the side ...
