Question
Chapter 12, Problem 7P
Interpretation Introduction
Interpretation:
The reason for the melting point of palmitic acid to be 6.5 degrees lower than stearic acid needs to be explained.
ConceptIntroduction:
The palmitic acid has lesser fatty acid compared to the stearic acid. The shortage ofVander Waals forces the palmitic acid is lower than 6.5 melting points. Van der Waals forces smaller, so it requires low energy to melt palmitic acid.

Draw the peptide Ala-Glu-Gly-Lys, as it would occur at physiological pH = 7.4. The R groups of Ala and Gly are not acidic or basic, therefore do not have a pka and the charge on these R groups is therefore independent of pH. Glu is acidic and Lys is basic, therefore the charge on these amino acids is pH dependent. The pKas are shown below. pKa N-term = 9.0 C-term = 3.5 Glu4.1 Lys = 10.5 2.
