# which of the following is not strictly a macromolecule?

( a ) protein
( b ) carbohydrate
( c ) lipids
( d ) nucleic acid

by definition the a macromolecule has molecular weight >800Da.. But lipids are very small.But still they still come under the category as they form vesicles upon acid digestion and the molecular weight of this vesicle is pretty high. Thus it is not "strictly" a macromolecule.
