    The glucan-chitin complex in Saccharomyces cerevisiae. IV. The electron diffraction of crustacean and yeast cell wall chitin (1982)
    New York : Wiley-Blackwell

    ISSN: 0006-3525

    Topics: Chemistry and Pharmacology
    Notes: Crustacean and yeast cell wall chitin were analyzed by means of transmission electron microscopy and selected-area diffraction. Single fibrils 8-25 nm wide have been observed in the micrographs of crustacean chitin. Analysis of a series of diffraction patterns obtained from thin crustacean chitin platelets yielded results which were in a better agreement with the theoretical structural model than those measured earlier. In this respect electron diffraction is shown to be superior to the more commonly used x-ray diffraction. Yeast cell wall chitin had a less perfect structure than the crustacean chitin. Single fibrils were not observed on the micrographs and electron diffraction patterns did not show any preferred fiber orientation. The evaluation of electron-diffraction patterns of both the primary septum and the adjacent circular zone of scar ring led to the conclusion that α-chitin is present in both these parts of the mother bud scar.

    Polydispersion in the diameter of fibers in fibrin networks: Consequences on the measurement of mass-length ratio by permeability and turbidity (1982)
    New York : Wiley-Blackwell
    Biopolymers 21 (1982), S. 1037-1047

    Topics: Chemistry and Pharmacology
    Notes: The diameters of the fibrin fibers in a clot are not uniform. Morphometric analysis of transmission electron micrographs show a bimodal distribution. The effect of polydispersity of fiber diameter on mass-length ratio calculated from the turbidity and permeability of a clot has been investigated with the aid of a two network model, the networks being called Major and Minor. The fibers in the Major network are many times thicker than those in the Minor network. In a model in which Major network fibers are 10 times thicker than fibers of the Minor network, the fibers in the Minor network make a negligible contribution to the turbidity of the clot. However, they may have a marked effect on its permeability. Experiments with clots made from human fibrinogen show that the Minor network is stabilized by α-polymer and γ-γ linkages and that without such linkages it is washed away during permeation. It remains relatively intact in crosslinked clots. In agreement with the theoretical model, when mass-length ratios calculated from the turbidity are compared with those calculated from the permeability, the latter were reduced in crosslinked clots with an intact Minor network.

    Three-dimensional structure of actinoxanthin. IV. A 2.5-Å resolution (1982)
    New York : Wiley-Blackwell
    Biopolymers 21 (1982), S. 287-300 
    Details
    ISSN: 0006-3525
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: The protein actinoxanthin (isolated from Actinomyces globisporus - molecular weight, 10,300; 107 amino acid residues) crystallizes in space group P212121 with cell dimensions: a = 30.9 Å, b = 48.8 Å, c = 64.1 Å, and Z = 4. The three-dimensional structure of actinoxanthin was determined by the x-ray multiple isomorphous replacement method at 2.5-Å resolution. The molecule is kidney-shaped and has a well-defined cavity. Its characteristic features are the absence of α-helices and the presence of enhanced content of antiparallel β-structure (∼55%). A cylinder-shaped formation of seven antiparallel β-strands comprises the main part of the protein structure. The established β-supersecondary structure is characterized by a three-dimensional topology similar to that of immunoglobulin domains, superoxide dismutase subunits, and azurin and plastocyanin proteins.

    Description / Table of Contents: Das Anfangsstadium der mit Phosphorsäure katalysierten Polykondensationsreaktion von Furfurylalkohol und Formaldehyd wurde untersucht. Die Bruttokinetik von Furfurylalkohol und Formaldehyd verbrauchenden Reaktionen wurde bei verschiedener Ausgangszusammensetzung der Monomeren und bei verschiedenen Temperaturen mit Hilfe analytischer und physikalischer (GPC) Methoden untersucht. Ein brauchbares NMR-Verfahren wurde für die quantitative Bestimmung der Methylen-und Methylenether-Bindungen in Abhängigkeit von verschiedenen Reaktionsbedingungen entwickelt.
    Notes: The initial stage of the phosphoric acid-catalyzed polycondensation reaction of furfuryl alcohol and formaldehyde was studied. The overall kinetics of monomer-consuming reactions were investigated in dependence of the initial monomer ratio and the temperature by analytical and physical (GPC) methods. A Suitable NMR technique was developed to determine the quantitative change in methylene and methylene ether linkages formed under different reaction conditions.

    Notes: The flow of molten poly(ethylene terephthalate) in pipes is discussed. The considerations made are based on the results of previous investigations by the authors, concerning the rheological behavior of the melt which exhibits thermal degradation. A procedure is proposed which enables the design of a pipe-line system for the distribution of molten, spinnable poly(ethylene terephthalate) in a fiber plant to be made.

    Compatibilization of the polystyrene/poly(ethyl acrylate) and polystyrene/polysoprene systems through ionic interactionsThis article is a review of work recently reported in the Journal of Polymer Science. (1982)

    Notes: Interactions between anions on one polymer chain with cations on another can lead to compatibilization of otherwise incompatible materials. Thus, if 5 mol% of ∼SO3H groups are attached to polystyrene, and 5 mol% of vinyl pyridine is copolymerized with ethyl acrylate, proton transfer occurs upon mixing, and the pairwise attractive interactions between the resultant ions compatibilize the blend. The same has been observed for the styrene-vinyl pyridine and sulfonated polyisoprene polymer pair. Dynamic mechanical and optical properties are used as a measure of compatibilization.

    Notes: The relations describing the elastic change of volume of thermoplastic cylindrical pressurized containers are presented. Discussions have been made on various cases including isotropic (i.e., un-oriented), uniaxially, and biaxially oriented materials. These relations are expected to be helpful for selecting the optimum processing conditions (i.e., draw ratio) in order to achieve the desired properties of polymeric pressurized containers.
