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.
The primary level of structure in a protein is the linier sequence of amino acids, formed by a condensation reaction (and therefore the abstraction of water) in protein synthesis. Each amino acid residue is then bonded via peptide bonds.herefore the amide planes define the polypeptide backbone. The secondary level of structure in a protein is the regular folding of the regions of the polypeptide chain. The two most common types are the alpha-helix and the beta-pleated sheet. Both myoglobin and haemoglobin are mostly made up from alpha-helices.
