Textbook Question
Chapter 3.8, Problem FQ
As stated, proteins are stereochemically pure because only a single enantiomer of each amino acid building block is used by nature. How many stereoisomers are possible for a chain of only 3 chiral amino acids if both enantiomers of the amino adds are used?
- 1. 2
- 2. 4
- 3. 8

Students have asked these similar questions
Which of the following statement about the conformation of protein is true?
a. Denaturation of protein causes the changes in the primary structure of the protein
b. Primary structure of protein refers to the sequence of amino acid linked by hydrogen bonds
c. Alpha-helix and beta-sheet are two types of secondary structures found in proteins
d. Amino acids are covalently linked by glycosidic bonds
5.
Arg and Lys
Asp and Lys
Pro and Glu
Among these amino acid combinations listed above, only the combination of Asp and Lys have side chains with groups that have the greatest ability to stabilize the tertiary structure of a protein.
Explain in your own words and by drawing (1) why Asp and Lys side chain interaction stabilizes the tertiary structure of a protein, and (2) why the pairs of Arg and Lys & Pro and Glu cannot provide the stability to the protein structure.
