![]() They are not complete amino acid chains, but they provide the parts and pieces for protein synthesis in the body. The versatility of peptides as a building block is evident through the introduction of reactive units that allow for more robust, stiffer covalently (or chemically) crosslinked hydrogel networks, a necessity for 3D printing of mechanically stabilized materials, to be prepared. This versatile methodology has the potential to have a transformational impact, opening the door for the rapid, facile, and modular synthesis of bioorthogonally reactive peptide probes. A buzz word in the current cosmetics and skincare industries, peptides are short-chain amino acids that are considered the building blocks of proteins. ![]() Following the development of a novel peptide coupling protocol for peptide synthesis in the presence of tetrazines, we successfully demonstrated its effectiveness and applicability. ![]() In this respect, peptides are powerful tools for the preparation of novel nanobiomaterials. This study demonstrated that the reaction undergoes a chemoselective ligation with unprotected peptides and proteins. Herein, we report the synthesis and development of a series of modular and versatile building blocks for inverse electron-demand Diels–Alder copper-free click chemistry: tetrazine-functionalized artificial amino acids. Cyclic Peptides: Building Blocks for Supramolecular Designs. The self-assembly of short peptide building blocks into well-ordered nanostructures is a key direction in bionanotechnology. Quanta BioDesigns building blocks for peptide synthesis enable SuperHydrophilic constructs and peptide modifications via our world-famous dPEG products. In this regard, the application of biologically and chemically orthogonal reactions to the design and development of novel radiotracers has the potential to have far-reaching implications in both the laboratory and the clinic. Abstract The need for post-synthetic modifications and reactive prosthetic groups has long been a limiting factor in the synthesis and study of peptidic and peptidomimetic imaging agents. To be brash, peptides are chains of amino acids bound together by peptide bonds, and when administered to the body they can have very great, and specific effects.
