(a)
Interpretation:
The number of tripeptides obtained from amino acids valine, lysine and phenylalanine needs to be determined.
Concept Introduction:
Amino acids are organic compounds containing amino as well as carboxylic groups. The general structure of an amino acid is shown as follows:
Here, R group is different for different amino acids.
These amino acids are linked through peptide bonds and results in the formation of protein. Thus, amino acids are simple unit of a peptide chain.
(b)
Interpretation:
The structural formula of tripeptides and their name according to shorthand abbreviation of amino acids needs to be determined.
