WebJan 13, 2024 · Amino acids like glutamic acid are examples of monomers. A monomer is a molecule that forms the basic unit for polymers, which are the building blocks of proteins. Monomers bind to other monomers to form repeating chain molecules through a process known as polymerization. Monomers may be either natural or synthetic in origin. Webdistribution of a polymer, and is defined by: Polydispersity index = Mw Mn The larger the polydispersity index, the broader the molecular weight. A monodisperse polymer where all the chain lengths are equal (such as a protein) has an Mw/Mn = 1. The best controlled synthetic polymers (narrow polymers used for calibrations) have Mw/Mn of 1.02 to ...
WebThe work presented in this thesis describes an innovative approach for biological sample preparation in a micro-volume syringe based on electrokinetic separation.
