Is Escherichia Coli Extract/sr-(Methionyl Tripeptide-46 Hexapeptide-40 Decapeptide-27 Methionyl s-Pig Polypeptide-2 Oligopeptide-234 sh-Oligopeptide-78) vegetarian?

This is a single chain recombinant peptide produced by fermentation in E. coli, with the final product containing residual E. coli host proteins. The starting gene is a fusion of genes coding for Tripeptide-46, Hexapeptide-40, Decapeptide-27, s-Pig Polypeptide-2, Oligopeptide-234, and sh-Oligopeptide-78; although the sequence name references pig-derived genetic sequence, the peptide is produced through microbial fermentation rather than direct animal extraction, though the pig-origin genetic template introduces some uncertainty for strict vegan classification.

An ingredient is considered vegetarian if it avoids components derived from killing an animal.

Classifications are made to the best of our knowledge based on available scientific and regulatory sources. We cannot guarantee the accuracy of every entry, errors in the sources we draw from can always occur. This tool also cannot account for cross-contamination, which depends entirely on individual suppliers and producers. If you believe a classification is incorrect, you can report an issue.
