in the end lipids are micromolecules or macromolecules?

when we conduct the test for marco and micro molecules lipids contained in cell membrane appears in as the retentate which indicate that it a macromolecule but actually its weight is less than 800 dalton which suggests that it is a micromolecule.

so they are counted as macromolecule but not strictly

lipids are macro molecules.lipids are indeed small in molecular weight but when we grind a tissue, we are disrupting the cell structure. the membrane form vescicles insoluble in acids pool in macromolecular fraction.
