Show answer
18-800 Daltons
The chapter specifies that biomolecules in the acid-soluble pool have molecular weights ranging from 18 to around 800 daltons.
Which of these is NOT a type of macromolecule found in living systems?
Show answer
Lipids
Proteins, nucleic acids and polysaccharides are the main macromolecules in living systems. Lipids are present in the acid-insoluble fraction because they are associated with membranes, but they are not strictly macromolecules. So the correct choice is lipids.
