A method for the determination of guanidoacetic acid and arginine in biological fluids,
(Elsevier, 1959-12)
A method for the determination of either arginine or guanidoacetic acid or both in biological materials has been presented. The method is based on the chromatographic separation of arginine from guanidoacetic acid and the ...
Synthesis of B vitamins by excised parts of White lupine seedlings grown in sterile culture
(Elsevier, 1954-09)
In this investigation it has been found that excised roots, hypocotyls, and epicotyls of White lupine seedlings synthesize thiamine, riboflavin, and niacin when grown in sterile cultures. Oxygen is necessary for this synthesis.
Palmityl coenzyme a deacylase
(Elsevier, 1959-06)
Enzymes have been found in various tissues which deacylate long chain fatty acyl CoA compounds. Methods of assay and the partial purification of palmityl CoA deacylase from pig brain are described.
The development of tyrosinase and cytochrome oxidase activity in mutants of Glomerella cingulata
(Elsevier, 1953-07)
Cytochrome oxidase activity in the standard type and in four mutants of Glomerella cingulata has been shown to be constant throughout the mycelial development. This enzyme is concentrated on mitochondria-like particles ...
Ion exclusion equilibria in the system glycerol–sodium chloride–water–Dowex-50
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1957-06)
Ion exclusion is an operation in which an ion exchange resin is used to separate an electrolyte from a nonelectrolyte in a polar solvent. An ion exchange resin tends to absorb a nonelectrolyte and to exclude an electrolyte. ...
The structural development of a bacterial virus
(Elsevier, 1952)
Bacteriophage precursors have been studied by breaking open infected bacterial cells and examining the intracellular material under the electron microscope. Bacterial breakage was accomplished by means of explosive ...
Heat transfer from superheated vapors to a horizontal tube
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1958-03)
Experimental data are reported for condensing Freon-114 (tetrafluorodichloroethane) and steam at several pressures. The condition of the vapors ranged from saturation to 180°F. of superheat. The condensing tube containing ...
