The Content Of Essential Amino Acids In 1950 Alfalfa Hay Grown In Utah Soil Treated With Different Fertilizers, Adriana Lanting Kunkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Application of fertilizers to soils to increase production yields has raised questions concerning the effect of fertilizer on chemical composition of plants. With the development of accurate, sensitive microbiological methods for the determination of amino acid in protein, speculations concerning amino acid content have been supplanted by acquisition of facts.

The effect of the different fertilizer applications on alfalfa yield has been discussed by Jones, et al (5). Also, some work has been done to determine the effect different fertilizers might have on the amino acid content of plant material. Some values (1,3,12) have been reported for the amino acid …

The Reaction Of Some Sodium Salts Of Fatty Acids And Benzoic Acid With Α-Bromobenzyl Cyanide, Richard W. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fife (4) and O'Shaughnessy (12) have made a series of di-esters by allowing the sodium salts of various fatty acids to react with ethyl monochloracetate according to the following equation:

RCO₂Na ≠ ClCH₂CO₂C₂H₅ ---------> RCO₂CH₂CO₂C₂H₅ ≠ NaCl .

The mechanism of the reaction appears to be ionic and to involve the attack of an RCO₂^- ion on the carbon atom to which the chlorine atom is attached. As the RCO₂^- approaches this carbon atom the chlorine atom moves …
