The molecular weight calculator recognizes both one-letter code for 20 natural amino acids, and three-letter code. When using the one letter notation, please type your peptide sequences in capital letters as single words (for example: AIVVG). When using the three-letter notation, separate amino...
Amino acids are one of the most common buffers in the human body - to learn more, check out our buffer calculator. How to use the protein molecular weight calculator? The protein mass calculator is the simplest tool you could imagine - just choose the desired combination of amino acids using...
The molecular weight (mw) of an oligopeptide or a protein can be determined by summation of the mw of its corresponding amino acid sequence. Certain modifications to this sequences can result in changes to the mw. This calculator provides the mw of an unmodified oligopeptide or protein. The ...
amino acid will absorb unusually strongly at 280nm. Tyrosine is one of the rarer amino acids, at ~3.25% in the average protein, so the same problem can occur to a lesser degree here also. So proteins of similar molecular weight can have quite different absorbances, since they can have ...

are presented. Both tools allow the calculation of peptide/peptoid chemical formulae and molecular weight, ChemDraw structure file export and automatic assignment of mass spectral peaks to deletion sequences and metal/protecting group adducts. Peptide Calculator also provides a calculated isoelectric poin...
For theoretical mass calculation in the peptide calculator, amino acid sequences for conglutin isoforms (Uniprot Q6PSU2-1, Q6PSU2-4 and Q647G9) were used, including the sequence conflicts. To take into account hydroxylation of proline as a posttranslational modification, partial reduction and ...
