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 ...
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 ...
Viscosity of dilute solutions of linear and branched polyvinyl acetate A preliminary account of this work was presented at the Ann Arbor High Polymer Research Conference, July 25, 1955.
(Interscience Publishers, Inc.Wiley Periodiocals, Inc., 1956-10)
The dilute solution viscosity properties of fractions of two linear and one branched sample of polyvinyl acetate in benzene and of two linear and one branched fraction in several solvents were measured at 35°C. Values of ...
The effect of polymyxin on plant roots
(Elsevier, 1955-10)
Root growth of young seedlings of barley and other species was substantially inhibited when placed in 5-10 p.p.m. solutions of the antibiotic, polymyxin B. The inhibiting effect was suppressed by simultaneous presentation ...
Variation of contact angle and structure with molecular length and surface density in adsorbed films of fatty acids
(Elsevier, 1956-02)
Films of fatty acids from 12 to 22 carbons were prepared by adsorption on glass microscope slides from cetane solutions. Variations in density were achieved (1) by using a range of concentrations with a fixed short time ...
The Raman spectra of four isotopic varieties of diborane in the gas phase
(Elsevier, 1958-02)
Raman spectra of the four isotopic species, 11B2H6, 11B2D6, 10B2H6, 10B2D6, in the gas phase have been obtained and interpreted in terms of the D2h bridge model. The results are in agreement with previous interpretations ...
Infrared spectra of high polymers. VII. Polyacrylonitrile Presented in part at the Symposium on Molecular Structure and Spectroscopy, Columbus, Ohio, June 1957.
(Interscience Publishers, Inc.Wiley Periodiocals, Inc., 1958-09)
The infrared spectrum of polyacrylonitrile has been obtained in the extended region of 70 to 3200 cm. −1 Polarized measurements were made on stretched and rolled specimens in the range of 350 to 3200 cm. −1 . An analysis ...
Mammalian tyrosinase: Effect of ions on enzyme action
(Elsevier, 1952-04)
1. 1. The univalent cations Li+, Na+, K+, and NH4+ have no effect on tyrosinase action.2. 2. The anions, fluoride, chloride, acetate, and oxalate, consistently inhibit the tyrosine-tyrosinase and dopa-tyrosinase reactions. ...
