The primary fragments are labelled according to their mass. Bottom: Fragmentation pattern of the measured amino acid spectra (lysine omitted), grouped by masses corresponding to the parent (i.e. intact) molecule (green), the amino acid without its −COOH group (red), the side chain of the...
The average molecular weight of an amino acid is 110Da. Dalton (Da) is an alternate name for the atomic mass unit, and kilodalton (kDa) is 1,000 daltons. Thus a protein with a mass of 64kDa has a molecular weight of 64,000 grams per mole. Peptide Bond Formation. R1 and R2 repre...
