1. Algorithms do not agree on any location for a beta sheet structure . 2. Other peptides that assume alpha-sheet structures include capped diphenyl-glycine-based dipeptides and tripeptides. 3. Fluorosilicate glass-ceramics with sheet structure , derived from mica, are strong and machinable. 4. "The balance sheet structure is expected to improve in the years ahead, " the company said. 5. There is also a large intracellular domain of the protein with a mixed alpha-helix / beta-sheet structure . 6. The ?-sheet structure extends to amino acids 53-57 of loop III . Here it forms a triple-stranded, antiparallel ?-sheet. 7. ?-pleated sheet structures are made from extended ?-strand polypeptide chains, with strands linked to their neighbours by hydrogen bonds. 8. In binding to the Kv1.2 channel the ?-sheet structure of the peptide Pi4 is thought to play an important role. 9. The beta-sheet structure and 16 half-cystines found in the molecule appear to yield a compact protein stable to acid and heat. 10. Funds raised through the sales will help to " improve its balance sheet structure , " the company said in a statement.
