Web1 de mai. de 1998 · One popular model for protein folding is the hierarchical model in which the formation of the tertiary structure of a protein is realized through the packing of elements of secondary structure including alpha-helices and beta-sheets. Although this model is appealing in its simplicity, a direct test of the model has not been demonstrated. WebProtein structures are made by condensation of amino acids forming peptide bonds. The sequence of amino acids in a protein is called its primary structure. The secondary …

WebA folded protein is analogous to a person sitting crosslegged on the floor, compared to the person standing bent over at the waist; one position requires less energy than the other. In theory, the same protein could assume many different stable, low-energy shapes. WebPrimary structure.
