Question

The substances which are not true bio-macromolecules but present as a structural component in all biological memb
(A) Polysaccharides
(B) Proteins
(C) Lipids
(D) Nucleic acids​

Answer 1

Answer:

nucleic acids

ANSWER

Biomolecules with molecular weights more than one thousand Dalton are called biomacromolecules. These are found in the acid-insoluble fraction. Lipids are not strictly macromolecules as their molecular weights do not exceed 800 Da but form a part of the acid insoluble pool. The molecules in the insoluble fraction with the exception of lipids are polymeric substances. Lipids are indeed small molecular weight compounds and are present not only as such but also arranged into structures like cell membrane and other membranes. So the acid insoluble fraction has only four types of organic compounds, proteins, polysaccharides nucleic acids and lipids but except for lipids none of them are micromolecules.

So the correct option is 'The compounds which are found in the acid insoluble fraction are called micromolecules'.
