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
