Mechanistic studies in porphobilinogen biosynthesis
(University of St Andrews, 1993) - Thesis[4-¹⁵c]ALA.HC1 (50% enriched) and [¹⁵N]ALA.HC1 (50% enriched) have been synthesised and utilised in mechanistic studies. The synthesis of the former was achieved via a modified literature procedure, employing [2-¹³C] glycine ... -
Asymmetric synthesis of amino acid derivatives as molecular probes for the mechanism of 3-methylaspsartate ammonia-lyase
(University of St Andrews, 1998) - Thesis3-Methylaspartate ammonia-lyase is a bacterial enzyme that catalyses the reversible elimination of ammonia, in the presence of monovalent and divalent metal ions, from (2S,3S)-3-methylaspartic acid to yield mesaconic acid. ... -
Synthesis of ganglioside analogues as biological probes for enzymes that modify sialic acids
(University of St Andrews, 1998) - ThesisGanglioside GM3, a glycosphingolipid found in the outer membrane of all mammalian cells, is expressed at much higher concentrations than normal in cancer cells. It has been reported that GM3 can inhibit signal transduction ... -
Studies of the interactions of resin acids with Pigment Yellow 13
(University of St Andrews, 1996) - ThesisThe surface interaction between Pigment Yellow 13, a classical diarylide pigment, and abietic acid type resin acids, used commercially to coat pigment products, was investigated by the joint techniques of solid-state ... -
The chemistry of seed oils: With particular reference to oils containing hydroxy and/or epoxy acids
(University of St Andrews, 1956) - ThesisPart I. Study of Fatty Oils Containing Epoxy and/or Hydroxy Acids An analytical procedure has been devised for the analysis of oils containing epoxy and/or hydroxy acids, and this has been applied to the examination of ...
