When you take cells or tissue pieces and grind them with an
acid in a mortar and pestle, all the small biomolecules dissolve
in the acid. Proteins, polysaccharides and nucleic acids are
insoluble in mineral acid and get precipitated. The acid soluble
compounds include aminoacids, nucleosides, small sugars etc.
When one adds a phosphate group to a nucleoside one gets
another acid soluble biomolecule called
