Question

17. List the 3-letter codes or the full names for the amino acids in the following pe Separate the codes/names by hyphens (e.g., aa1-aa2-aa3-etc). (12 pts) (a) Peptide 1: WESTERN (b) Peptide 2: ISAGREAT (c) Peptide 3: PLACEINWA (d) Estimate the overall charge on each peptide at physiological pH. (3 pts) Peptide 1: Peptide 2: Peptide 3: 18. Suppose you wanted to make a buffer of exactly pH 7.00 using KH2PO4 and Na2HPO4. If the final solution was 0.1 M in KH2PO4, what concentration of Na2HPO4 would you need? (7 pts)

Explanation / Answer

WESTERN:Tryptophan-Glutamic acid-Serine-Threonine-Glutamic acid-Arginine-Aspargine

ISAGREAT: Isoleucine-Serine-Alanine-Glycine-Arginine-Glutamic Acid-Threonine

PLACEINWA: Proline-Leucine-Alanine-Cysteine-Glutamic acid-Isoleucine-Aspargine-Tryptophan-Alanine
