Answer (a.) If compound X form monomer A and compound Y form monomer B

And monomer A and B form polymer C.

Any type of acidic and basic amino acid are accepted in this question

Compounds X and Y are acidic amino acid and basic amino acid, respectively.
While monomers A and B are formed by modifying compounds X and Y by
maintaining the basic structure of amino acid. Polymer C is formed through a
condensation reaction of monomers A and B.
(a) Identify the possible structural formulae (according to the type of
hydrogen) of Monomer A, Monomer B and Polymer C.
(b) Construct table that includes the hydrogen type, chemical shift,
integration number, multiplicity and adjacent hydrogen for Monomer A,
Monomer B and Polymer C.
(c) Identify the possible structural formulae for repeating unit of Polymer
C.
(d) Identify the possible structural formulae of compound X present in
aqueous and basic solutions.
(e) Discuss the differences between compound Y with aliphatic carboxylic
acid.

Definition Definition Large and very high-molecular-weight substances that consist of hundreds to thousands of repeating units. Polymers are also known as macromolecules. Number-average-molecular weight is the measuring system for the polymers.

The order of amino acids in a protein is the
As we’ve discussed, a peptide bond is made when amino group of one amino acid combines with the carboxylic acid group of another amino acid (releasing a water molecule in the process). The C-N bond formed in this process is called a peptide bond. Peptide bonds have a few properties that might be unexpected. b) Another observation is that although the N-H of the peptide bond is able to serve as a H-bond donor the N atom of the peptide bond does not serve as an effective H-bond acceptor. Provide an explanation for this observation, using Lewis structures, VSEPR theory and/or valence bond theory as appropriate.c) It is also fairly accepted that while proteins undergo dynamic motions and conformational changes, and while R groups can freely rotate about Cα, it is generally not possible to freely rotate around a peptide bond.
