beta-sheet to alpha-helix conversionThe effect on protein conformation and thermal stability was studied for beta-Galactosidase (beta-Gal) encapsulated in the nanopores of a silicate matrix (E beta-Gal). Circular dichroism spectra showed that, compared with the enzyme in buffer (S beta-Gal), E...
Alpha Helix and Beta Sheet The primary structure of a protein is the amino acid sequence of the polypeptide chain. The way the polypeptide chain forms hydrogen bonds determines the secondary structure. There are two main types of secondary structures in proteins, alpha helices and beta pleated ...
This section provides a quick introduction of protein secondary structures, alpha helix and beta sheet. Both structures are stabilized by hydrogen bonds between oxygen atoms and hydrogen atoms of two amino acid residues lined up side by side.©...
The FTIR spectra and 1H and 13C solid-state NMR results indicate that the peptides, arranged mostly in a beta-sheet structure in feather, reorganize into a mainly alpha-helix and less beta-sheet mixed secondary structure, when self-assemble from the solution at room temperature. MALDI-ToF-...

The meaning of ALPHA-HELIX is the coiled structural arrangement of many proteins consisting of a single chain of amino acids stabilized by hydrogen bonds.
Describe alpha helix and beta sheet (give examples). What contributes to the secondary structure of a protein? Protein: Protein is a large, complex macromolecule found in all living things. Proteins perform a variety of cruc...

Polypeptides prepared from the racemic Boc-D,L-Lys NCA are unlikely to have secondary structures like α-helix and β-sheet. Kinetics analysis We studied the kinetics of LiHMDS-initiated polymerization for BLG NCA, Boc-D,L-Lys NCA and Boc-L-Lys NCA. The rate of polymerization, kp[I], ...
