  • Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

    Creator:
    Venier, Lynn Corrine
    Abstract:
    In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...

  • Preparation and properties of poly-L-tyrosyl acetamidinated ribonuclease

    Creator:
    Lynn, Jackson
    Abstract:
    Polypeptidyl derivatives of bovine pancreatic ribonuclease (RNase) containing two or three tyrosine chains with an average of two to three residues per chain have been prepared. The effects of various perturbants such as neutral salts, ethanol, urea and guanidine hydrochloride on the thermal transition of the derivatives have been studied....

  • The urea denaturation of bovine serum albumin, polyglycyl bovine serum albumin and poly-L-phenylalanyl bovine serum albumin

    Creator:
    Chung, Po-luen
    Abstract:
    A comparative study was made on the effect of urea denaturation of bovine serum albumin (BSA), polyglycyl BSA and poly-L-phenylalanyl BSA. The denaturation process was followed by ultraviolet spectrophotometry and optical rotation. A blue shift in the absorption maximum at 278 mμ was observed in urea denatured proteins, In 7M...

  • Atmospheric transport of anthropogenic semi-volatile organic compounds to the Olympic Peninsula of Washington State

    Creator:
    Killin, Robert K.
    Abstract:
    Ambient high-volume (hi-vol) air samples were collected between March 15th and May 30th 2002, at Cheeka Peak Observatory (CPO), located on the tip of the Olympic Peninsula, Washington State. This sampling campaign was in conjunction with the 2002 Inter-Continental Transport and Chemical Transformation (ITCT 2K2) Campaign and the Photochemical Ozone...

  • X-ray structure studies of oriented phospholipid multilayers

    Creator:
    Lytz, Robert Keith
    Abstract:
    Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...

  • Protein synthesis in Sarcophaga bullata

    Creator:
    Allen, Robert Roy
    Abstract:
    An investigation was made into certain aspects of protein synthesis at different developmental stages of the flesh fly Sarcophaga bullata. This included measurements of the incorporation of labeled amino acids into protein by intact cells from a single organ, the larval fat body, and a study of amino acid activating...

  • Measuring in situ biotransformation in BTEX-contaminated groundwater

    Creator:
    Alumbaugh, Robert E.
    Abstract:
    Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

  • A microcomputer automated anodic stripping voltammetric analyzer for trace heavy metal speciation

    Creator:
    Dewald, Lamar Robert
    Abstract:
    An automated instrument based on a single-board microcomputer was developed for use in voltammetric analyses. Operator input of numerous experiment parameters allows any type of voltammetric analysis to be implemented and multiple scans to be run unattended. A three operational amplifier potentiostat is used to control the cell voltage and...

  • Pathways of glucose utilization and ribose synthesis in the chick embryo

    Creator:
    Coffey, Ronald Gibson
    Abstract:
    The production of C¹⁴O₂ metabolized from glucose labeled in specific carbon atoms by homogenates of chick embryonic and adult heart was compared by the radiorespirometric technique. Homogenates of early (two to five days of incubation) embryo hearts were found to utilize the phosphogluconate pathway of glucose catabolism to a greater...

  • Preparation and properties of polyglycyl insulin

    Creator:
    Wu, Lily Henson Liu
    Abstract:
    In order to understand more about insulin behavior in solution, Zn-free insulin was modified by adding polyglycyl chains to the molecule and then observing the effect of the peptide on the behavior of insulin under various conditions. NCA-glycine (N-Carboxyglycine anhydride) of high purity was reacted with Zn-free insulin in aqueous...
