About Peptide Calculator 1.0.1
This Peptideweb.com application is tool to calculate the molecular formulae, accurate monoisotopic and average masses of your peptide. You can work with a sequence in one- or three-letter amino acid code, choose few popular modifications on N- and C-terminals or add disulfide bridges.
The masses are calculated using the following atomic weights:
Element Monoisotopic mass Average mass
H 1.0078250 1.0079400
C 12.0000000 12.0110000
O 15.9949146 15.9994000
S 31.9720718 32.0660000
N 14.0030740 14.0067400
