Consider a 0.317L solution of the amino acid glutamic acid(0.575M), which has the alpha carboxylic group (pKa=2.10), an alpha amine group(pKa=9.47), and a carboxylic acid group in the side chain(pKa=4.10). If the titration is started at a very low pH, how many litres of 2.27M NaOH would you need to addto reach the isoelectric point of the amino acid?

Consider the amino acid histidine, whose side chain pKa = 6.0. Explain what would happen to the histidine pKa if inside of a protein a positively charged lysine was brought into close proximity of the histidine. Do you think the Histidine pKa would increase, decrease, or remain the same? Explain WHY you chose your answer.

Explain why gelatin, which is mostly collagen, is nutritionally inferior to other types of proteins. Globular proteins are typically constructed from several layers of secondary structure, with a hydrophobic core and a hydrophylic surface. Is this true for a fibrous protein such as B-keratin? Briefly explain your answers for the following questions. a) Is Trp or Gln more likely to be on a protein’s surface? b) Is Ser or Val less likely to be in a protein’s interior? c) Is...
