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 21 proteinogenic Î±-amino acids found in eukaryotes, grouped according to their side chains' pKa values and charges carried at physiological pH 7.4. Amino acids are organic compounds containing amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side chains of certain amino acids.
