    Abstract : The product R1-MR2E is an ester formed from an esterification of a carboxylic acid and an alcohol at Cambrex Karlskoga AB. The production of the intermediate R1-MR2E is a large-scale production and there are two main objectives and two sub-objectives that this project aims to study of the manufacturing. READ MORE

  4. 3. 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

  5. 4. Minimization of chemical's release from a large-scale pharmaceutical industry : By optimization of the crystallization process

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Cecilia Rahn; [2021]
    Keywords : Minimization of release; pharmaceutical industry; crystallization; optimization; Minimering av utsläpp; läkemedelsindustri; kristallisation; optimering;

    Abstract : The presence of active pharmaceutical ingredients (APIs) and other chemicals in wastewater has caused concerns in recent years due to its potential risk to the environment and society. Thus, the aim of the study is to investigate ways to minimize the release of chemicals from a large-scale pharmaceutical industry to an industrial wastewater treatment plant. READ MORE

  6. 5. Mathematical modeling of fatty acid metabolism during consecutive meals and fasting : New insights into fatty acid regulation based on arterio-venous data

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Kajsa Tunedal; [2021]
    Keywords : Systems Biology; fatty acid metabolism; modeling;

    Abstract : Obesity, type 2 diabetes, and cardiovascular diseases are major problems in today's society, causing millions of deaths every year. One of the main risk factors for these diseases is a dysregulation of the fatty acid metabolism, where the balance between release and uptake of fatty acids is disturbed. READ MORE
