Summary
Hybrid macromolecules were created using peptides and dendrons, enabling precise control over their structure. Designed folding and assembly properties resulted in a unique dendronized bundle of alpha-helices.
Area of Science:
- Macromolecular science
- Supramolecular chemistry
- Biomaterials
Background:
- Peptides and dendrons are well-defined building blocks for macromolecular construction.
- Their monodisperse and sequence-defined nature facilitates precise molecular design.
Purpose of the Study:
- To investigate the formation of hybrid macromolecules using peptide and dendron components.
- To explore the self-assembly and folding properties of these novel hybrid structures.
Main Methods:
- Synthesis of peptide-dendron hybrid macromolecules.
- Characterization of molecular structure and folding.
- Analysis of self-assembly behavior.
Main Results:
- Peptide-dendron hybrids were successfully synthesized as monodisperse and sequence-defined macromolecules.

Amyloid Fibrils
13.0K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Protein Organization
10.1K
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.

Protein Folding
12.6K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

Peptide Bonds
86.7K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...
