  2. Reversible addition−fragmentation chain-transfer polymerization

    en.wikipedia.org/wiki/Reversible_addition%E2%88...

    Specific materials and their applications include polymer-protein and polymer-drug conjugates, mediation of enzyme activity, molecular recognition processes and polymeric micelles which can deliver a drug to a specific site in the body. [19] RAFT has also been used to graft polymer chains onto polymeric surfaces, for example, polymeric ...

  3. Biopolymer - Wikipedia

    en.wikipedia.org/wiki/Biopolymer

    More specifically, polypeptides like collagen and silk, are biocompatible materials that are being used in ground-breaking research, as these are inexpensive and easily attainable materials. Gelatin polymer is often used on dressing wounds where it acts as an adhesive.

  4. Peptide - Wikipedia

    en.wikipedia.org/wiki/Peptide

    There are numerous types of peptides that have been classified according to their sources and functions. According to the Handbook of Biologically Active Peptides, some groups of peptides include plant peptides, bacterial/antibiotic peptides, fungal peptides, invertebrate peptides, amphibian/skin peptides, venom peptides, cancer/anticancer peptides, vaccine peptides, immune/inflammatory ...

  5. Protein structure - Wikipedia

    en.wikipedia.org/wiki/Protein_structure

    The two ends of the polypeptide chain are referred to as the carboxyl terminus (C-terminus) and the amino terminus (N-terminus) based on the nature of the free group on each extremity. Counting of residues always starts at the N-terminal end (NH 2 -group), which is the end where the amino group is not involved in a peptide bond.

  6. Elastin-like polypeptides - Wikipedia

    en.wikipedia.org/wiki/Elastin-like_polypeptides

    Elastin-like polypeptides (ELPs) are synthetic biopolymers with potential applications in the fields of cancer therapy, tissue scaffolding, metal recovery, and protein purification. For cancer therapy, the addition of functional groups to ELPs can enable them to conjugate with cytotoxic drugs. [ 1 ]

  7. Peptide library - Wikipedia

    en.wikipedia.org/wiki/Peptide_library

    With 7 possibilities at Residue 2 and 20 possibilities at Residue 3, the total would be or 140 different polypeptides in the library. This peptide library would be useful for analyzing the effect of the post-translational modification acetylation on lysine which neutralizes the positive charge. Having the library of different peptides at ...

  8. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    In general, polypeptides are unbranched polymers, so their primary structure can often be specified by the sequence of amino acids along their backbone. However, proteins can become cross-linked, most commonly by disulfide bonds , and the primary structure also requires specifying the cross-linking atoms, e.g., specifying the cysteines involved ...

  9. Lifson–Roig model - Wikipedia

    en.wikipedia.org/wiki/Lifson–Roig_model

    In polymer science, the Lifson–Roig model [1] is a helix-coil transition model applied to the alpha helix-random coil transition of polypeptides; [2] it is a refinement of the Zimm–Bragg model that recognizes that a polypeptide alpha helix is only stabilized by a hydrogen bond only once three consecutive residues have adopted the helical conformation.
