1) A dipeptide is a peptide made of two amino acids connected through a peptide bond. a) Based on our discussion of amino acids and peptide structures, draw the best full Lewis structure of a dipeptide made from two trifluoroalanine amino acids. (Trifluoroalanine is a nonstandard, or noncanonical, amino acid that can be synthesized by chemists but is not found in nature.) Be sure to include the position of all lone pairs in your structure. The sidechain in a trifluoroalanine amino acid has the formula CF3. b) Would you say there are any ionic bonds in this structure? Briefly explain why or why not. C) in your structure, which bond(s) have the least equal sharing of electrons between the two bonded atoms? d) In your structure, which bond(s) have the most equal sharing of electrons between the two bonded atoms?

Transcribed Image Text:1) A dipeptide is a peptide made of two amino acids connected through a peptide bond.
a) Based on our discussion of amino acids and peptide structures, draw the best full
Lewis structure of a dipeptide made from two trifluoroalanine amino acids.
(Trifluoroalanine is a nonstandard, or noncanonical, amino acid that can be
synthesized by chemists but is not found in nature.) Be sure to include the position of
all lone pairs in your structure. The sidechain in a trifluoroalanine amino acid has the
formula CF3.
D) Would you say there are any ionic bonds in this structure? Briefly explain why or why
not.
C) In your structure, which bond(s) have the least equal sharing of electrons between the
two bonded atoms?
d) In your structure, which bond(s) have the most equal sharing of electrons between the
two bonded atoms?
