Concept explainers
a.
To draw:
The structure of amino acid represented by “Pro”.
Introduction:
Amino acids contain a protonated
b.
To determine:
The structure of amino acid represented by “N”.
Introduction:
Amino acids contain a protonated amine and a carboxylic acid in the form of carboxylate ion. These two functional groups are bonded to a central carbon atom called the alpha-carbon. Amino acids have both three-letter and one-letter abbreviations. The three letter abbreviations were used first, but to sequence longer chains of amino acids, it was reduced to a single letter to transfer data more easily.
c.
To determine:
The structure of amino acid represented by “Val”.

d.
To determine:
The structure of amino acid represented by “Y”.
