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.
Generally, proline is an amino acid that causes a turn. The amino acids G, A, V, I, S, T and C are more likely to cause beta sheets, whereas the others cause alpha helices. polypeptide chains fold into functional protein becasue of four types of protein structure. 1) The primary structure- the unique sequence of chain of amino acids 2) The secondary structure- when the certain amino acids become linked by hydrogen bonding, either Beta-pleated sheeting or alpha-helixes are formed. this starts the folding of the polypeptide chain into a protein
