larger side chains would result in more restrictions and consequently a smaller allowable region in the Ramachandran plot.
side chain of W (tryptophan) is larger than C (cystiene), cystiene side chain stearically more free than tryptophan residue.
Which amino acid is likely to have a more restricted Ramachandron plot? W or C? Please...
Which amino acid below is most likely to be found at the surface of a protein in its native fold? a) valine b) leucine c)phenylalanine d)lysine Please explain
Which amino acid is most likely to be found in the core of a protein?
Is more polar amino acid will have more affinity toward stationary or mobile phase . Is less polar amino acid will have more affinity toward stationary or mobile phase.
B. Explain how two amino acid residues can form a peptide bond I was able to get A) in this but I don't seem to understand this completely.
Which of the following amino acids is the least reactive? a. met b. ser c. cys d. tyr The answer is A) Methionine. but i do not understand why? like as far as amino acids go how do i know by looking at them which would be a more reactive amino acid or which are less reactive?
Question 11. Certain amino acids destabilize or prevent formation of alpha-helices. Which amino acid is more likely to be found in these structures based on its charge and R-group size? A. Glycine B. Proline C. A sequence of several Glutamate D. A sequence of several Lysine E. Alanine Question 12. Which of the following is least likely to result in protein denaturation? A) Altering net charge by changing pH B) Changing the salt concentration C) Disruption of weak interactions by...
a) which amino acid tested is most polar?
b) look up the structure of the amino acids. explain why it
makes sense that the amino acid you listed is more polar than the
others?
c) what amino acids are in the fruit juice?
D. CHROMATOGRAPHY Chromatography is a general technique that is used to separate various materials. In this case, students can use the unique chemistry of the amino acid to determine its migration in a specific solvent. The solutions...
please show work and explain
I have attached a titration of a mock amino acid with OH-. I have labeled the different charge states of the amino acid as I, II, III, IV. I have labeled different points on the titration curve as A, B, ....G. I want you to tell me which form(s) of the species I, II, III or IV predominates (is present at greatest concentration) at each of the lettered points on the curve. I would also...
Hydro- phobic +2 Hydro- philic 200 50 100 150 Amino acid number 4. Based on the hydropathy plot above, if amino acid # 1 is extracellqlar, please draw a diagram of the polypeptide in the context of a phospholipid bilayer. Is the arrow pointing to an intracellular or extracellular loop? Is the C terminus intracellular or extracellular (10 points)? (*Assume the hydrophobic regions form transmembrane a helixes.)
Hydro- phobic +2 Hydro- philic 200 50 100 150 Amino acid number 4....
Given the Nature of the ATP molecule, which of the amino acids is most likely to be found in a protein site that interacts with the triphosphate portion of ATP? Please explain why.
