Methods of ab initio prediction of alpha helices, beta sheets, and polypeptide tertiary structuresThe present invention provides a novel four stage ab initio approach for predicting the tertiary structure of polypeptides. The methods of the invention combine the classical and modem views of protein ...
Protein secondary structure: alpha-helices and beta-sheets, hairpins and loops, stabilization by hydrogen bonds
There are two main types of secondary structures in proteins, alpha helices and beta pleated sheets. The hydrogen bonding pattern of the amino acids in the polypeptide chain determine whether an alpha helix or a beta pleated sheet will form. Polypeptide chains can have alpha helices, beta ...
Alpha helices and beta pleated sheets are the two most commonly found secondary structures in apolypeptidechain. These two structural components are the first main steps in the process of folding a polypeptide chain. Thekey differencebetween Alpha Helix and Beta Pleated Sheet is in theirstructure; ...
Answer to: Compare and contrast the molecular structures of alpha helices and beta sheets in proteins, including at least two similarities and two...
The two common types are alpha helices and beta sheets, stabilized by hydrogen bonds between amino acid residues. Answer and Explanation: The hydrogen bonds found in an alpha helix and beta sheets are primarily formed between the carbonyl oxygen atom of one ...
Thesaurus Medical Encyclopedia Related to Alpha-helix:Beta-sheet alpha helix n. A secondary structure of proteins, characterized by a single, spiral chain of amino acids stabilized by hydrogen bonds. [Fromalpha-form,the form taken by unstretched protein molecules.] ...
Beta sheets can be relatively flat or to some extent twisted, which makes them more structurally diverse than alpha helices.

Transgenetic studies argue that these PrP isoforms interact during the formation of PrPSc, which involves the unfolding of one or more helices of PrPC followed by refolding into beta-sheets. PrP residues 109-122 (H1), which were predicted to be alpha-helical, form beta-sheets in aqueous ...
The three-dimensional arrangement of alpha-helices, beta-sheets, and other parts of the polypeptide chain is called: a. primary structure b. secondary structure c. tertiary structure d. quaternary structure What determines wheth...
