Question
Chapter 12, Problem 6P
Interpretation Introduction
Interpretation:
The reason for the oleic acid to have alower melting point related to stearic acid needs to be explained.
Concept introduction:
The oleic acid has a low melting point because fatty acid in the oleic acid is not stronger than the intermolecular forces. The melting pointof saturated fatty acid addition with increasing molecular weight.

- Peptides. 1. 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.
