Question
Chapter 25.4, Problem 25.11P
Interpretation Introduction
(a)
Interpretation:
The product formed when the protein reacts with the excess of an acid needs to be determined.
Concept Introduction:
The proteins act as buffer for the body and they do not let the overall pH of the body to go beyond a certain limit and this happens due to the carboxylate anion and ammonium cations.
Interpretation Introduction
(b)
Interpretation:
The structure formed needs to be drawn when the protein reacts with excess base.
Concept Introduction:
The protein acts as a buffer for the body and maintains the pH of the body by means reacting with bases and acids. The carboxylate ion reacts with the acids and the ammonium end of the protein reacts with base or the nucleophiles.

Lysine and tryptophan are two amino acids that contain an additional N atom in the R group bonded to the a carbon. While lysine is classified as a basic amino acid because it contains an additional basic N atom, tryptophan is classified as a neutral amino acid. Explain why this difference in classification occurs.
1. (a) Draw a circle around one amino acidin the structure. (
b) Draw a box around one amino acid side chain.
(c) Indicate whether the side chain you chose is hydrophobic or hydrophilic.
(d) Draw an arrow pointing to a peptide bond
2. If the peptide segment shown above was part of a beta sheet, which of its functional groups would be involved in forming and stabilizing the beta sheet?
3. Which amino acid (also called amino acid residue)would be more likely to occur on the surface of a protein: an aspartate residue or a methionine residue? Explain your choice.
Your task is to categorize and tabulate the 20 standard
amino acids with the following columns:
1. Amino Acid Full Name (alphabetical order)
2. One letter abbreviation
3. Three-letter abbreviation
4. Structure of R-group (if you will present the full
picture of the amino acid, encircle or highlight the R
group)
5. Classification (1, 2, 3 or 4)
6. Essential or Non-Essential Amino Acid (research on
this; write E for Essential & NE for Non-Essential)
7. Use/ Function of Amino Acid
