  1. 1. Genetically modified tobacco (Nicotiana tabacum) plants for an increased production of wax esters

    Kandidat-uppsats, SLU/Dept. Of Plant Biology

    Författare :Linn Nilsson; [2022]
    Nyckelord :Wax esters; metabolic engineering; nicotiana tabacum; fatty acid reductase; phytyl ester synthase;

    Sammanfattning : Wax esters (WE) are naturally occurring lipids consisting of a fatty acid bound to a fatty alcohol with an ester bond. As an alternative to petrochemicals, plant-derived WE:s are of considerable commercial interest as lubricants, but have in recent years also received great attention for their potential as a starting material for bio-fuel production.

  3. 2. Microgels as drug carriers : Relationship between release kinetics and self-aggregation of the amphiphilic drugs adiphenine, pavatrine and diphenhydramine.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för läkemedelskemi

    Författare :Lobna Ali Mohsen; [2021]
    Nyckelord :Amphiphilic drugs; small angle x-ray scattering; macrogels; binding isotherm; CMC; self-aggregation; phase structure; micelles.;

    Sammanfattning : Abstract There has been great interest in microgels as drug carriers within the pharmaceutical industry. This includes the use of amphiphilic drugs for treating conditions such as depression, allergies, and cancer. LÄS MER

  4. 3. Coupling of substances containing a primary amine to hyaluronan via carbodiimide-mediated amidation

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för biokemi och organisk kemi

    Författare :Hotan Mojarradi; [2010]
    Nyckelord :carbodiimide; hyaluronan; optimization; EDC; NHS; tyramine;

    Sammanfattning : The purpose of this study was to investigate the carbodiimide-mediated amidation of hyaluronan (HA). The carbodiimide-mediated amidation includes the formation of a urea derivative, O-acylisourea, between the carbodiimide and a carboxylic group of HA, which a primary amine can displace, resulting in an amide bond.
