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.
Except for glycine, amino acids (AA) in peptides, proteins, and physiological fluids have asym-. metricalcarbonsandexistprimarilyintheL-configuration relative to L-glyceraldehyde. There are. more than 700 AA in nature, but only 20 of them (alanine, arginine, asparagine, aspartate, cysteine, glutamate, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phe-. nylalanine, proline, serine, tyrosine, threonine, tryptophan, and valine) are building blocks for. proteins in cells (1).
