Question

After grinding a living tissue in trichloroacetic acid and then staining it, you would obtain two fractions, i.e. acid soluble fraction and acid insoluble fraction. Acid insoluble fraction does not contain (A) nucleic acids (B) polysaccharides (C) lipids (D) flavonoids and alkaloids

Tardigrade Admin · Accepted Answer

Flavonoids and alkaloids are secondary metabolites. These are with very less molecular weight (i.e. less than 1000 dalton). Thus, are not found in acid insoluble fraction, as this fraction comprises of biomacromolecules.

nucleic acids

polysaccharides

lipids

flavonoids and alkaloids

Flavonoids and alkaloids are secondary metabolites. These are with very less molecular weight (i.e. less than $1000$ dalton). Thus, are not found in acid insoluble fraction, as this fraction comprises of biomacromolecules.
