WebbThe isoelectric point is defined as the pH at which a particular amino acid sequence (peptide chain) bears no net electrical charge. At this pH the the amino acid sequence forms a zwitterion. The calculation is based on the pK values of the amino acids and of the terminal amine & carboxyl group of the peptide chain. tekla user guideWebbAmino acids are the compounds or building blocks that make up peptides and proteins. Each amino acid is structured from an amino group and a carboxyl group bound to a tetrahedral carbon. This carbon is designated as the α-carbon (alpha-carbon). Amino acids differ from each other with respect to their side chains, which are referred to as R groups. tekla powerfab estimatingDeamidation is a chemical reaction in which an amide functional group in the side chain of the amino acids asparagine or glutamine is removed or converted to another functional group.
