Understanding Peptide Sequences and Naming Conventions

Peptide product names often combine a short code, a number, and sometimes a suffix — and at first glance this can look fairly opaque. Here is a general explanation of what is usually going on.

Where the Codes Come From

Many peptide names are abbreviations related to their discovery, structure, or the research area they are associated with. Numbers frequently relate to the sequence length or a specific fragment/analogue variant.

Why Naming Matters

Small naming differences (for example, the presence or absence of a suffix like “DAC” or a fragment number) can indicate a meaningfully different compound. Always check the full product name and description rather than relying on a shortened or remembered version.

When in Doubt

If you are unsure whether a listing matches the exact compound you are looking for, check our Peptide Glossary or contact us directly before ordering.
