Intro to Biochemistry (Murphy 301) CH 1 – 4 Questions and Answers The side chain of histidine has a typical pKa value in the range of 6.5-7.4. However, when analyzing the pKa values in a particular protein, scientists determined that one particular His residue has an unusually low pKa value of 4.8. Which of the following statements correctly explain this anomaly? 1) The microenvironment around a residue can impact its pKa value. 2) A positively charged amino acid must be in close proximi...

The right-handed alpha helix - Answer - An example of secondary structure; the alpha helix found in proteins is RIGHT-HANDED; spirals upwards in the counterclockwise direction About the alpha helix - Answer - AA side chains and H atoms on each alpha carbon project out from the axis; no noticeable hole in the middle because of atomic radii - intramolecular H bonds connect the carbonyl C of one aa residue to the peptide H in the 4th residue - H-bond are nearly parallel to the axis of the hel...
