Peptides are short strands of amino acids that are increasingly used therapeutically, as biomaterials and as chemical and biological probes. The capacity to isolate, manipulate and label peptides and larger proteins is limited, however, by the ability to reliably attach functional molecules, such as fluorescent compounds, to peptides in locations that won't affect the three-dimensional structure and function of the short amino acid strand.
虎扑电竞ers are most interested in adding functional molecules to the N-terminus, or the end of a peptide with a free amine group (NH2), of an amino acid strand in order to minimize the inter
