In this note we display an observation about the geometrical properties of the gauge group manifold of the standard electroweak theory, and the values of the gauge coupling constants. Heuristically obtained stucture relates the value 137.036... to the low energy U(1) coupling. The constuction resembles techniques recently used within the framework of the string and D-brane theory. We consider this as an indication that the string theory has direct relevance for the phenomenological QFT and particle physics.
