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.
Below the 20 most common amino acids in proteins are listed with their three-letter and one-letter codes: Charged (side chains often make salt bridges): â¢ Arginine - Arg - R â¢ Lysine - Lys - K â¢ Aspartic acid - Asp - D â¢ Glutamic acid - Glu - E Polar (usually participate in hydrogen bonds as proton donors or acceptors):
