Primary amino acid sequence of EPA and tryptic peptide coverage map for EPA produced following processes A or B, and identification of post-translational modifications (PTM) by LC/MS/MS. Bold text indicates peptides not identified in tryptic peptide mapping. Specific PTMs observed in both technical replicates at >1% intensity are noted by the colored highlighted letter(s) (gray for gluconylation, yellow for acetylation and green for amidation) and italics designates N-terminal modifications. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
