- Below is the structure of glycine. Draw a tripeptide composed exclusively of glycine. Label the N-terminus and C-terminus. Draw a box around the peptide bonds.Most proteins contain more than 100 amino acid residues. If you decided to synthesize a “100-mer,” with 20 different amino acids available for each position, how many different molecules could you make?which two amino acid have two chiral center？ I know Isoleucine contain two chiral center，how about another AA？
- Why do we not indicate the side chains of the amino acids that form the peptide bond (see Figure 3.10)?say you have been asked to determine the molecular structure of a soluble protein with roughly 500 amino acids per subunit. you think there may be a lysine and aspartic acid interaction so but you want to get molecular conformation. what structural technique would you utilize in order to picture this interaction and what resolution would be needed?How many carbon atoms are present in the R group in each of the following standard amino acids? Please see picture. Thank you!
- how would you name the peptides here? (I circled the R groups and drew dotted lines to represent hydrogen bonding)I was given an amino acid position 564 with the PDC code 2V1X. Would it be possible to describe why this position in the protein is important and outline the effects the mutation will have on the structure / function of the protein? Thank you.Some bacteria produce poly-γ-glutamic acid, a polymer in which the amino group of each glutamate residue is condensed with the γ-carboxylate group of the adjacent residue. Draw the repeating structure of this polymer.
- A peptide in a solution with a pH of 7 has the following sequence: K-R-E-D-H-D-E (Lys-Arg-Glu-Asp-His-Asp-Glu). To get to the pI, you would need elevate the pH.Draw the structure of peptide with the following amino acids Gly-Leu-Ala-Gly-Pro-Hyp. The structure formed of the peptide is most likely a? Please explain. Thank you!Poly- L -leucine in an organic solvent such as dioxane is α helical, whereas poly- L -isoleucine is not. Why do these amino acids with the same number and kinds of atoms have different helix-forming tendencies?
