Lehninger Principles of Biochemistry 习题答案chapter 19
Polyglutamate, a polypeptide made up of only L-Glu residues, has the -helical conformation at pH 3. However, when the pH is raised to 7, there is a large decrease in the specific rotation of the solution. Similarly, polylysine (L-Lys residuesl is an helix at pH 10, but when the ...
