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 num... more

550.79 GHz.
This can be calculated using the formula for the frequency of a rotational transition:
ν = (2B(J+1) - 2BJ) / c
where ν is the frequency of the transition, B is the rotational constant, J is the initial rotational quantum number, and c is the speed of light.
Solving for B and plugging in the given values for ν and J, we get:
B = νc ... more
