What is Gluteomorphin and Why Does the Food Zoomer Test for It?

Gluten-derived opioid-like peptide

Gluteomorphin is a short peptide fragment derived from gluten proteins. Measuring immune responses to it (IgA and IgG) helps reveal peptide-level reactivity and whether immune activity is more mucosal or systemic.

About Gluteomorphin

Overview and History

Gluteomorphin (also reported as gliadorphin or gliadin exorphin) is a peptide produced when gluten proteins are broken down. Biochemically it belongs to a class of small peptide fragments that were identified in studies of gluten digestion and peptide bioactivity. These fragments have been shown in laboratory studies to interact with opioid-type receptors and to influence local gut signaling and motility. In a clinical testing context, gluteomorphin is evaluated as a specific antigen to detect antibody responses that reflect immune recognition of these gluten-derived peptides.

Interpreting Highs and Lows

Elevated antibody responses to gluteomorphin may indicate increased immune recognition of gluten-derived peptide fragments and can be associated with greater mucosal exposure or systemic antigen presentation; elevated IgA suggests a mucosal response, while elevated IgG points to broader systemic recognition. Low or absent antibody responses typically reflect limited immune recognition, possible tolerance, or low recent exposure to the peptide. Any single gluteomorphin result is most informative when interpreted alongside other Food Zoomer markers (other gluten peptides, transglutaminase-associated markers, and the IgA/IgG balance) and clinical context.

Featured Test

Gluteomorphin is included in the Food Zoomer to provide peptide-level resolution within the gluten family. Testing antibodies to this fragment complements gliadin and related markers, helping clinicians distinguish localized mucosal activity from systemic patterns and refine individualized dietary and monitoring decisions.

Gluteomorphin FAQs

What is Gluteomorphin and why is it important?

Gluteomorphin is a small peptide made when certain gluten proteins are broken down. It can act as an opioid-like fragment that interacts with gut signaling and immune components. Measuring whether the immune system recognizes this specific peptide helps show more detailed patterns of food-related immune activity.

What does it mean if my Gluteomorphin levels are low?

Low antibody levels to gluteomorphin generally mean there is little immune recognition of that specific gluten fragment—this can reflect limited exposure or immune tolerance. By contrast, higher antibody levels suggest stronger immune awareness of gluten-derived peptides. Always consider low or high results together with other Food Zoomer findings and clinical information.

What does it mean if my Gluteomorphin levels are high?

Elevated antibodies to gluteomorphin suggest greater immune recognition of gluten-derived peptide fragments and may reflect increased mucosal exposure (when IgA is elevated) or broader systemic response (when IgG is elevated). High levels point to a pattern of peptide-specific reactivity but do not by themselves indicate a specific health status; interpretation requires the full panel and clinical context.

Why is Gluteomorphin included in the Food Zoomer?

Including gluteomorphin adds peptide-level specificity within the gluten group, allowing providers to detect clustered reactivity that whole-protein tests can miss. This helps differentiate mucosal versus systemic antibody patterns and supports more precise, pattern-based dietary and monitoring decisions.
