  • Some biochemical studies of phenylmercuric acetate and mercuric acetate toxicity in rats

    Creator:
    Ellis, Robert William
    Abstract:
    Biochemical studies of phenylmercuric acetate (PMA) and mercuric acetate toxicity in rats carried out during this investigation were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral ingestion, (2) the effect on some soluble enzyme activities and determinations of ²⁰³Hg binding in the enzyme fractions,...

  • Investigations into the mechanism of the photodechlorination of pentachlorobenzene

    Creator:
    Schmidt, Robert Dean
    Abstract:
    Several experiments were undertaken to investigate the mechanism of photodechlorination of pentachlorobenzene. The thermal methoxydechlorination reaction of pentachlorobenzene was studied. In DMSO at 50 °C sodium methoxide reacts smoothly with pentachlorobenzene to give three tetrachloroanisole isomers. A second-order kinetic plot for this reaction is linear to high precision, indicating that...

  • An investigation of the thermal stability of polyglycyl bovine serum albumin

    Creator:
    Harris, Ward Edwin
    Abstract:
    A heat stable derivative of bovine serum albumin containing 300 residues of glycine added to 30 sites on the surface of the protein has been prepared. This derivative may be heated to 100° C for prolonged periods of time without aggregation. By comparison, native BSA aggregates at 62° C under...

  • 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...

  • 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...

  • Studies of the functional tyrosyl residues of insulin

    Creator:
    Papaioannou, Stamatios Evangelos
    Abstract:
    Acetylimidazole was used to acetylate the tyrosyl residues of insulin. The kinetics of acetylation were studied by termination of the reaction at several time intervals, isolation of acetylated insulin and determination of 0-acetyltyrosyl groups by deacetylation with hydroxylamine. The deacetylation was also studied kinetically by means of the absorbancy change...

  • 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....

  • 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 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...
