  • The constitution of β-glucosan and its relationship to glucose, starch and cellulose 

    Oldham, John Walter Hyde (University of St Andrews, 1923) - Thesis
    The thesis is divided into two parts, which in turn are subdivided as follows: Account of the various methods for the preparation of glucosan. Proof of the constitution of glucosan, together with the general problem of its ...
  • The molecular constitution of inulin 

    McOwan, George (University of St Andrews, 1923-04) - Thesis
    The investigation on inulin, which forms the subject of the present thesis, is an extension of the earlier work of Irvine and Steele, who placed the study of this polysaccharide on an exact basis.
  • Investigations on cellulose 

    Robertson, George James (University of St Andrews, 1924-06) - Thesis
  • The constitution of glucose diacetone 

    Cramond, George Alexander (University of St Andrews, 1925-03) - Thesis
    The reaction which takes place between acetone and sugars or polyhydric alcohols, first described by Fischer, produced several beautiful crystalline compounds of greater interest. Their value, however, to the study of ...
  • The labile nature of the halogen atom in organic compounds 

    Traill, David (University of St Andrews, 1925-10) - Thesis
  • The molecular structure of inulin 

    Stevenson, John Whiteford (University of St Andrews, 1928-04) - Thesis
  • The structure of benzylidene alpha methylglucoside and of 2:3 dimethylglucose 

    Purves, Clifford B. (University of St Andrews, 1929-02) - Thesis
    After discussing the condensation portion of methylglucoside with benzaldehyde and the chemistry of the product, the structure of benzylidene methylglucoside, together with that of the dimethyl glucose, is reviewed. A few ...
  • The acetylation and methylation of starch 

    Rutherford, Jean Kerr (University of St Andrews, 1931-09) - Thesis
    The colloidal nature of starch, and the high molecular weight of the complex has rendered it impossible to study the constitution of this polysaccharide by other than degradation reactions. Accordingly starch has been ...
  • The constitution of starch : a study of the methyl, acetyl, and benzoyl derivatives of starch 

    Caldwell, Walter Anderson (University of St Andrews, 1934-01) - Thesis
    The field of the Chemistry of Starch is so wide and the complexities involved are so great that any attempt to solve the problems of the constitution of starch cannot be spread over the whole front, but must necessarily ...
  • Walden inversion in the pentose series 

    Honeyman, John (University of St Andrews, 1944-01) - Thesis
    The interconversion of sugars in nature has for long been a source of interest and speculation. Many attempts were made to postulate a mechanism for the smooth and facile transformations but until 1933 the theories were ...
  • Studies on absorption from mammalian intestine 

    Wood, Helen Ogilvie (University of St Andrews, 1945-02) - Thesis
  • Researches in the terpene series 

    Cuthbertson, William Wilson (University of St Andrews, 1945-12) - Thesis
  • Photo-conduction in semi-conductors 

    Caldwell, John Bell (University of St Andrews, 1948-04) - Thesis
    This thesis is largely concerned with the phenomenon of photo-conduction in micro-crystalline layers of lead sulphide, antimony sulphide and thallium sulphide. All the materials studied are semi-conductors, either excess ...
  • Experiments in connection with the structure of emetine 

    Norcross, Geoffrey (University of St Andrews, 1949-01) - Thesis
    Emetine is the principal alkaloid of ipecacuanha root which is obtained from the plant known botanically as Psychotria Ipecacuanha, also called Cephaelis Ipecacuanha, indigenous to Brazil, and from Psychotria Acuminata ...
  • Stereochemical researches of reduced quinolines 

    Davidson, Walter Lamb (University of St Andrews, 1949-01) - Thesis
    The chapter of stereochemistry which deals with the attempted resolution of saturated tervalent nitrogen compounds is a long and interesting one, but is as yet incomplete. The problem has been attacked in many ways; but ...
  • Researches into the structure of emetine 

    Battersby, A. R. (Alan Rushton) (University of St Andrews, 1949-04) - Thesis
    The first crude preparation of the alkaloid emetine was obtained in 1817 by Pelletier from the plant species Cephaelis ipecacuanha. Since that day many workers have turned their attentions to the structural problem presented ...
  • The condensation of open-chain glucose derivatives with derivatives of the normal form of glucose and related studies 

    Mitchell, Alan Thomas Smith (University of St Andrews, 1949-09) - Thesis
    The condensation of simple aliphatic and aromatic aldehydes and of ketones with cyclic and acyclic glucose derivatives has been considerably investigated and, thus, isopropylidene, ethylidene, benzal and many similar and ...
  • Research into the structure of the alkaloid aspidospermine 

    Smith, G. F. (George Fouet) (University of St Andrews, 1949-10) - Thesis
  • Studies on palm oil with special reference to interestterification 

    Kifli, Hamirin Abdul (University of St Andrews, 1981) - Thesis
    Interesterification which can be considered as the removal of fatty acids at random from glyceride molecules, the shuffling of these acids and their replacement of the glyceride molecules, has been investigated for palm ...
  • Studies of some fused imidazole derivatives 

    Moody, David John (University of St Andrews, 1986) - Thesis
    The main synthetic routes to benzimidazole N-oxides are outlined and some indication is given as to the current and potential pharmacological usefulness of such materials. A claim that 4-methyl-2-nitrophenylglycine is ...
