protein
'Protein' and 'Gluten' both have to do with protein substances. 'Protein' is the general term: it can be a nutrient in many foods or a biological molecule. 'Gluten' is much more specific. It is a mixture of proteins in certain types of grain, for example wheat, and is important in baking. The words can be confused because gluten consists of proteins. But not every protein is gluten. When speaking generally about protein in nutrition, you say 'Protein'. When it is about grains, flour, bread, or intolerance, 'Gluten' fits.
