A typical 1/4 cup serving of all-purpose flour contains 3.2 grams of protein (10.3 g per 100 g), which makes it a moderate source of protein. That covers roughly 6% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 11% of the calories in all-purpose flour come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 111 grains in the database, all-purpose flour ranks 77th by protein per serving, and 585th out of all 796 foods on the site. Set against dinner roll, another grain entry in the database, a serving carries about 0.5 g more protein (dinner roll has 2.7 g per 1 roll).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 31.3 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
