Functional peptides can perform different biological and engineering functions through sequence and structural design. Cell-penetrating peptides are primarily used to improve the cellular uptake and intracellular delivery of macromolecular and hydrophilic cargoes; targeting peptides increase ...
Peptide drugs consist of specific amino acid sequences and can exert their effects through receptor agonism or antagonism, regulation of enzymes and ion channels, interference with protein-protein interactions, and targeted delivery. Their molecular size lies between that of conventional ...
