(2019-12-06)As concerns about climate change continue to intensify, one way to motivate companies to take meaningful climate action agnostic to political intervention is identifying economically attractive strategies to mitigate COv2 ...
-
(Texas A&M University. Libraries, 1978)The basic goal of this study was the development of an efficient approach to the total synthesis of vernolepin. Special attention was paid to the development of an efficient synthesis of bicycle[4.3.1]-dec-3-en-9,10-diones ...
-
(Texas A&M University. Libraries, 1982)The asymmetric syntheses of N-protected-(alpha)-amino acid derivatives are reported. Deprotonation of N-benzoylglycine (-)-menthol ester (1) with lithium diisopropylamide (LDA) affords the stable dilithio derivative (9). ...
-
(Texas A&M University. Libraries, 1980)Electron micrographs of endosperm tissue from germinating seedlings of Ricinus communis L. cv Hale show the presence of proplastids which contain prominent starch grains. The content of starch in the tissue was found to ...
-
(Texas A&M University. Libraries, 1987)The role of folates in the enzymatic formation of the porphyrin macrocycles was investigated. Uroporphyrinogen III cosynthetase-free hydroxymethylbilane synthase from Rhodopseudomonas spheroides was incubated with the ...
-
(Texas A&M University. Libraries, 1990)Ruthenium metal on a zeolite support was found to be active for the catalytic synthesis of ammonia from dihydrogen and dinitrogen at temperature between 300 and 450°C and at atmospheric pressure. A triply-promoted iron ...
-
(Texas A&M University. Libraries, 1990)With dioxygen-saturated (1 atm, 2.1 mM) dimethyl sulfoxide solutions that contain aniline (1-15 mM), the addition of excess hydroxide ion (10:1 HO-/PhNH2) yields approximately two superoxide ions (O2-), one azobenzene, and ...
-
(Texas A&M University. Libraries, 1989)Seven woody landscape ornamentals were grown in a glasshouse under wellwatered conditions and screened for water consumption, net assimilation rate (NAR) and water use efficiency. Lagerstroemia indica 'std. purple' L had ...
-
(Texas A&M University. Libraries, 1992)Chapter II describes the synthetic application of a non-heme monooxygenase from Pseudomonas oleovorans (POM) toward the preparation of a series of epoxides from their protected allylic alcohol precursors. Like other ...
-
(Texas A&M University. Libraries, 1992)The synthetic utilities of enzymes as catalysts for asymmetric synthesis have been explored in several aspects. Fructose-1,6-diphosphate aldolase from rabbit muscle and E. coli, rhamnulose-1-phosphate aldolase and ...
-
(Texas A&M University. Libraries, 1987)Several aspects of the use of enzymes as catalysts in organic synthesis have been explored. The stability of the enzyme glucose dehydrogenase useful in reduced nicotinamide cofactor (NAD(P)H) regeneration has been studied. ...
-
(Texas A&M University. Libraries, 1988)Immobilized glucose dehydrogenase from Bacillus sp. was found to be a practical catalyst for NAD (P) H regeneration. It is very stable at high temperatures. Coupled with an appropriate alcohol dehydrogenase, several compounds ...
-
(Texas A&M University. Libraries, 1990)Several aspects of the use of enzymes in organic synthesis have been explored. Fructose-1,6-diphosphate aldolase (FDP aldolase) is available commercially and has been cloned and overexpressed in E. coli. Both aldolases ...
-
(Texas A&M University. Libraries, 1992)Two of the key enzymes in the biosynthetic pathway of sialic acids were studied. A highly expressed CMP-sialic acid synthetase with a decapeptide tag attached at the C-terminal of the enzyme and the wild type enzyme from ...
-
(Texas A&M University. Libraries, 1988)Initially, assay conditions were established for the fatty acid elongation and desaturation pathways of bovine liver and adipose tissue microsomes; rat liver microsomes were used as a reference. Rat liver elongation activity ...
-
(Texas A&M University. Libraries, 1986)Two experiments were performed in order to determine the methionine and choline requirements for maximum protein synthesis by primary cultures of chick hepatocytes. In experiment 1, a 4 x 8 factorial design was employed ...
-
(Texas A&M University. Libraries, 1990)In this study attempts were made to synthesize Ru3(CO)12 inside the 13A supercages of NaY zeolite and to evaluate the encapsulated product as a catalyst for the hydrogenation of CO2 to CH4. Characterization by IR and ...
-
(Texas A&M University. Libraries, 1987)Elastase (EC 3.4.21.11) is normally involved in the degradation of elastin, and is believed to be the primary agent responsible for the induction of several degenerative connective tissue diseases. The primary subsite ...
-
(Texas A&M University. Libraries, 1993)This dissertation discusses the use of Lewis acids to activate and catalyze cyclization and addition reactions of aminyl radicals generated from N-hydroxypyridine-2-thione carbamates to unsaturated systems under very mild ...
-
(2009-05-15)The synthesis of solid state materials has traditionally been accomplished using rigorous heating treatments at high temperatures (1,000°C) to overcome the slow rate of diffusion between two reactants. Re-grinding and ...
