Question
A MALDI-TOF spectrum was obtained for a fragment of the neuropeptide ACTH:
Arg-Pro-Val-Lys-Val-Tyr-Pro-Asn-Gly-Ala-Glu-Asp-Glu-Ser-Ala-Glu-Ala-Phe-Pro-Leu-Glu-Phe
It's monoisotopic mass [M] = 2462.198
These cations have the following monoisotopic masses:
H*
= 1.00
Nat = 22.99
K* = 39.10
Calculate the [M+H]* peak for ACTH, round your value to the nearest whole number.
