Wheat flour gluten proteins and their link to celiac disease
What it found
Lab tests on commercial wheat flour found that a gliadin extract also contained other gluten proteins.
The researchers then checked how these fractions reacted with the main marker linked to celiac disease.

Animal and lab studies
Proteins in gliadin extract
In lab tests, the gliadin portion pulled from commercial wheat flour was not pure. It also contained glutenin proteins and avenin-like proteins.
Testing for celiac markers
After identifying the proteins, the researchers used two lab methods to check how different gluten fractions reacted with the main marker tied to celiac disease.
What the authors conclude
- They say that accurately identifying prolamins is needed to understand how each fraction affects the start of celiac disease.
- Their work shows that extracts thought to be pure gliadin actually contain other protein types as well.
How it was done
Certain gluten peptides can trigger celiac disease in people who are genetically prone to it. Because all gluten proteins look very similar, scientists do not yet know how much each one contributes to the condition.
Researchers extracted proteins from store-bought wheat flour and separated them using lab equipment. They identified the proteins in the richest gliadin portions using mass spectrometry. They then tested several gluten fractions for reactivity to the main celiac disease marker using two lab methods.
What it can’t tell you
- We summarised it from the abstract only.
- These are lab tests on flour proteins, not studies in people.
- They cannot show what happens when someone eats wheat flour or whether these proteins cause symptoms.
