Peptides are third one of our main research and application. It is short polymers formed from the linking of (usually ≤100) amino acids. They comprise some of the most basic components of human biological processes, including enzymes and hormones. The link between one amino acid residue and the next is known as a peptide bond or an amide bond .
Driving the therapeutic implementation of peptides is the Human Genome Project, which led to the initial sequencing of DNA to identify ~20,000–25,000 genes of the human genome from both a physical and functional standpoint. A recent report by market and technology research indicated that >40 approved peptide-based drugs are in use today, and ~800 are being developed to treat allergies and cancer as well as Alzheimer’s, Huntington’s, and Parkinson’s diseases. Peptides typically offer low toxicity and high specificity, and they demonstrate fewer toxicology issues.
