The calculator allows to determine the molecular weight of an amino acid sequence. Additionally posttranslational modifications can be added.
Amino Acid Library
1. Animated Structure: The chemical formula of the currently selected amnio acid is displayed.
2. Properties : The properties of the currently selected amnio acid are displayed.
3. Sorting Criteria: Amnio acids can be sorted by class, alphabetically or by molecular weight.
4. Switch Views: Tap to switch between the library and the calculator.
1. Sequence View:
The result and the sequence view are displayed. To add an amnio acid tap an amino acid field at the bottom. To change the sequence tap the according sequence part. A table will appear. It is possible to delete an amino acid or replace an amino acid. To replace an amino acid tap and select the desired amino acid.
