In the article, it explains how to use objectdataprovider and bind too fields together. In my case, I just want to bind one control-text to a objectprovider and pass value to the objectprovider throught parameter. chong Tuesday, May 09, 2006 7:29 PM
The alpha helix (Î±-helix) is a common secondary structure of proteins and is a righthand-coiled or spiral conformation (helix) in which every backbone N-H group donates a hydrogen bond to the backbone C=O group of the amino acid four residues earlier (hydrogen bonding).ifferent amino-acid sequences have different propensities for forming Î±-helical structure. Methionine, alanine, leucine uncharged, glutamate, and lysine (MALEK in the amino-acid 1-letter codes) all have especially high helix-forming propensities, whereas proline and glycine have poor helix-forming propensities.
Primary Structure (Peptide Bonds) The primary structure of a protein consists of amino acids chained to each other. Amino acids are joined by peptide bonds. A peptide bond is a type of covalent bond between the carboxyl group of one amino acid and the amino group of another amino acid. Amino acids themselves are made of atoms joined together by covalent bonds. Secondary Structure (Hydrogen Bonds) The secondary structure describes the three-dimensional folding or coiling of a chain of amino acids (e.g., beta-pleated sheet, alpha helix).
