Concept explainers
(a)
Interpretation: A condensed structural formula for the peptide, threonylserine has to be drawn.
Concept introduction: In the IUPAC naming of a peptide, full name is written for the amino acid which is present on the far right. The other amino acid residues in the peptide receive “shortened” names that end in –yl. The –ine or –ic acid ending of the amino acid names is replaced by –yl.
(b)
Interpretation: A condensed structural formula for the peptide, valylglycylcysteine has to be drawn.
Concept introduction: In the IUPAC naming of a peptide, full name is written for the amino acid which is present on the far right. The other amino acid residues in the peptide receive “shortened” names that end in –yl. The –ine or –ic acid ending of the amino acid names is replaced by –yl.
