1. 1. Exploring Regioselective 5N-acylation of Neuraminic acid

   University essay from Lunds universitet/Kemiska institutionen

   Author : Simon Hans Lilje; [2022]
   Keywords : acylation; amide; antibacterial drugs; regioselective deprotection; sialic acid; organic chemistry; Chemistry;

   Abstract : In this project, a regioselective method to deprotect and acylate the amide on C5 of sialic acid is explored. Sialic acid is one of the most complex monosaccharides and is an important ligand in many higher organisms in intercellular cell communication. The most prominent example is related to the immune system. READ MORE

3. 2. The Effect of Using DMSO as a Cosolvent for Ligand Binding Studies

   University essay from Lunds universitet/Biofysikalisk kemi

   Author : Simon Birgersson; [2019]
   Keywords : Galectins; Nuclear Magnetic Resonance; NMR; Biophysical Chemistry; Relaxation; CPMG; ITC; Biofysikalisk Kemi; Kärnmagnetisk resonans; Technology and Engineering; Chemistry; Biology and Life Sciences;

   Abstract : DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. READ MORE

4. 3. Trapping social wasps, in apple orchards and vineyards with synthetic volatiles and live yeast cultures in Scania, Scandinavia

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Malin Iris Dörre; [2015]
   Keywords : Vespinae; social wasps; lure; semiochemicals; yeast; apple; grapes;

   Abstract : Social wasps (Hymenoptera, Vespinae) foraging for carbohydrate nutrients are a major pest, particularly in berry and fruit orchards. The identification of volatile attractants for social wasp management is accordingly an urgent research challenge. Overripe fruit and fermenting sweet baits are since long known to attract wasps.

5. 4. Synthesis towards an aromatic alfa-dixyloside

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Martin Olofsson; [2015]
   Keywords : Synthesis; Proteoglycan; Glucosaminoglycan; Xylose; Carbohydrate; Glycosylation; Organic chemistry; Chemistry;

   Abstract : A proteoglycan is a protein with at least one glycosidic chain or glycosaminoglycan (GAG) covalently bound to it. Since a common linker between the core protein and the GAG chain has a xylose present, the biosynthesis of GAGs can be primed using xylosides containing hydrophobic aglycons providing that these xylosides are capable of penetrating the cell membrane.

6. 5. Synthesis of α1,2- and α1,6, linked Dimannosides for Analysis of Protein Carbohydrate Interactions

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Ann-Kathrin Saur; [2011]
   Keywords : Synthesis; Carbohydrate; Selectivity; Protein; Analysis;

   Abstract : The aim of the project was to synthesize α1,2-linked and α1,6-linked dimannosides linked through either an oxygen-atom or a sulphur-atom, and subsequently test the binding properties of the dimannosides to lectins with known specificity towards mannose-containing glycans. Thedimannosides were prepared by a glycosylation reaction using selectively protected monosaccharides containing a thiol or alcohol nucleophilic glycosyl acceptor and a series of different glycosyl donors.
