- In α-helices - what is the length of the hydrogen bonds between: TYR41H and GLU37O ALA39H and MET35O GLU38H and ILE34O THR36H and ARG32O. ARG32H and TYR28OBeta ( ? ) sheets are a type of secondary structure in proteins. A segment of a single chain in an antiparallel ? sheet has a length of 80.5 Å . How many residues are in this segment?Chemistry Draw the stable form of the peptide Ser-Trp-Glu-Asp-Cys-Asn at pH 10.40. Be sure to explicitly label every N, O, S as well as H that is not attached to carbon in the main chain and indicate a rectangle to identify the six atoms that are coplanar with the peptide bond between residue 2 and 3 in the peptide
- Reposting - What would the tertiary structure of the dipeptide Asp-Ser be if it was made into a polypeptide chain? (Would it form a beta pleated sheet, an alpha helix, etc) Why would it do this? What properties of this polypeptide causes this? This sub part still needs to be solved - What would the tertiary structure of Pro-ala and Glycl-L-alanine be?Vertebrate proteins? What is meant by the term polypeptide backbone?A. Write the structure of the following peptide at pH 5.0 and calculate its net charge at this pH. Asp-His-Tyr-Arg-Lys-Leu-Thr-Gln. Based on the pKa value of the ionizable groups. B. A polypeptide consisting only of L-glutamate residues (poly-L-glutamate) may have a random coil or helical structure depending on pH. Explain this behavior by indicating at what pH values the helical structure will be favored.

Draw it and make sure to - draw it as a physiological PH (\7.4) - Label the N-terminus and the C-terminus of the dipeptide. - Draw a circle around the peptide bond. (only circle one bond)
- Predict the secondary and tertiary structure of the following peptide sequence: a.) LKAENDEAARAMSEA b.) CRAGGFPWDQPGTSN 2.) In an experiment, you somehow added cysteine so that it would covalently bond a protein complex composed of two proteins. But, the problem is you can’t detect the bridge, meaning you can’t detect covalent bond formation of cysteine in between two proteins. How do you generate disulfide bond? Give an idea to force disulfide bond formation between two proteins. 3.)Lysozyme consist of 4 disulfide bridges while Bovine Serum Albumin(BSA) is 17. However, lysozyme is more rigid compared to BSA.
