A. Write the structure of the pentapeptide GLDSC. B. What is the complete name of this pentapeptide? Show a tertiary structure of ACGGC after a disulfide bond forms. A sample of an unknown peptide was divided into two aliquots. One aliquot was treated with trypsin; the other was treated with cyanogen bromide. Given the following sequences (N-terminal to C- terminal) of the resulting fragments, deduce the sequence of the original peptide.
