Your opinion is in fact wrong. Or, at least, it's phrased in a way that is just-barely not true.
Glucose is a catch-all term referring to both chains and cycle structures based on a certain "base" of atoms, and that base is chiral -- it is different from its mirror image. Glucose thus refers to both L-glucose and dextrose. You can process both in some ways -- they both taste sweet to you. But you can't metabolize L-glucose, because the first step uses a similarly chiral enzyme called hexokinase, which only fits properly with dextrose.
Most lab synthesis of glucose (which is to say, pretty much all lab synthesis which is not bio-synthesis) is symmetric under mirror reversal and thus produces 50% dextrose, 50% L-glucose. So about half of the glucose synthesized in a lab requires special evolution on the part of humans to process.
