    Calculation of Peptides Formed After Chemotrypsin Treatment of Polypeptide

    Chemotrypsin is a proteolytic enzyme that cleaves peptide bonds after the amino acid residues like phenylalanine, tryptophan, and tyrosine. When the polypeptide Lys-Phe-Gly-Asp-Trp-Ser-Arg-Trp-Leu-His is treated with chemotrypsin, it undergoes hydrolysis to form several peptides. The calculation of the number of peptides can be done as follows:

    Step 1: Identify the amino acid residues that can be cleaved by chemotrypsin. In this case, the residues are Phe, Trp, and Arg.

    Step 2: Divide the polypeptide into smaller peptides by cleaving the peptide bond after these residues. The possible peptides that can be formed are:

    1. Lys
    2. Phe-Gly-Asp
    3. Trp-Ser
    4. Arg-Trp-Leu-His

    Step 3: Count the number of peptides formed. In this case, four peptides are formed.

    Therefore, the correct answer is '4'.
