The physical and chemical properties of eumelanin

Pigment Cell & Melanoma Research, 2006
SummaryIn this article, we review the current state of knowledge concerning the physical and chemical properties of the eumelanin pigment. We examine properties related to its photoprotective functionality, and draw the crucial link between fundamental molecular structure and observable macroscopic behaviour.

Chondronectin: Physical and chemical properties

Archives of Biochemistry and Biophysics, 1985
Chondronectin, the chondrocyte attachment factor, was purified from chicken serum and characterized as to its physical and chemical properties. From sedimentation equilibrium data it was found to have a native molecular weight of 175,800 +/- 800 and a subunit molecular weight of 55,540 +/- 800 in the presence of guanidinium chloride and cysteine ...

Physical-chemical properties of ubiquitin

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1980
The secondary structure of ubiquitin, the environment of its single tyrosine residue and its potential for interacting noncovalently with histone 2A or DNA, have been probed by circular dichroism (CD), ultraviolet absorbance, fluorescence and ancillary techniques.

Physical-Chemical Properties

1987
Among the nucleic acids, the single-stranded RNA molecules have the highest potential to form a large variety of structures and to undergo quite different structural transitions. The determination of their structure and structural transitions is a prerequisite for understanding their function in replication, transcription, translation, and regulation ...

Chemical and physical properties of phosphamidon

1971
Phosphamidon (C10H19C1NO5P) is a broad-spectrum systemic insecticide (Bachmann et al. 1956 and 1957) of the vinyl phosphate group, comprising a mixture of cis- and trans-isomers in the proportion 73: 27. It was first prepared by Beriger and Sallmann (CIBA Ltd. 1955, Anliker et al. 1961 a).

Chemical and physical properties of radionuclides

International Journal of Radiation Applications and Instrumentation. Part B. Nuclear Medicine and Biology, 1987
There are many radionuclides with a wide range of energies and half-lives available for use as non-sealed radiotherapeutic agents. To date, no single radionuclide has emerged as being clearly superior to all others, in the way that 99mTc predominates in diagnostic imaging. It is unlikely that one will emerge.

Physical and chemical properties of myelin

Archives of Biochemistry and Biophysics, 1963
Abstract Electron micrographs of a myelin fraction prepared from bovine white matter showed myelin lamellae structures and indicated that the preparation was relatively free of contaminating material. The fraction was solubilized by surfactants, after which phase solubility and moving-boundary electrophoresis showed that the bulk of the preparation ...

Interrelationships of Physical and Chemical Properties of Kaolinites

Clays and Clay Minerals, 1966
AbstractRank-correlation coefficients are utilized to show relationships between physical and chemical properties of Georgia and English kaolins. Montmorillonite impurity in the Cretaceous kaolins shows high level correlations with magnesium, iron, silica-alumina ratio, CEC, water sorption, surface area, sediment volume, and Brookfield viscosity ...

Physical and chemical properties of radionuclide therapy

Seminars in Radiation Oncology, 2000
As more radionuclide therapies move from laboratory feasibility studies into clinical reality, it becomes increasingly important for the labeling chemistry to produce consistently a stable radiopharmaceutical that remains intact under the challenge of human catabolism.
