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 amino acids, nucleosides, small sugars etc. When one adds a phosphate group to a nucleoside one gets another acid soluble biomolecule called

For analysis of a living tissue sample, we first grind it in trichloroacetic acid (Cl_3C.COOH) using a mortar and a pestle and obtain a thick slurry. Then, after straining the slurry through a cheese cloth, we obtain two fractions, viz, one is filtrate (or acid-soluble pool) and the other retentate (or acid-insoluble fraction). We observed that all the small biomolecules are present in the filtrate. Whereas, proteins, polysaccharides and nucleic acid get precipitated. The acid soluble compounds include amino acids, nucleosides, small sugars, etc. When one adds a phosphate group to a nucleoside one gets another acid soluble biomolecule. Could you guess its name?

An acid soluble compound formed by phosphorylation of nucleoside is called (A) Nitrogen base (B) Adenine (C) Sugar phosphate (D) Nucleotide

Take a living tissue, grind it in trichloroacetic acid using pestle and mortar, and then strain it, you would obtain two fractions : acid-soluble and acid-insoluble fraction. Acid-insoluble fraction does not contain

Take a living tissue, grind it in trichloroacetic acid using pestle and mortar, and then strain it, you would obtain two fractions : acid-soluble and acid-insoluble fraction. Acid-insoluble fraction does not contain

A 5.82 g silver coin is dissolved in nitric acid. When sodium chloride is added to the solution, all the silver gets precipitated as AgCl. The percentage of silver in the coin is :

Take a living tissue, grind it in trinchloroacetic acid using pestle and morta, and then strain it, you would obtain two fractions : acid-soluble and acid-insoluble fraction. Acid-insoluble fraction does not contain

Building blocks of proteins are amino acids and that of polysaccharides are monosaccharides. Many polysaccharides are called homopolymers but all proteins are known as heteropolymers. b) Give one example for a homopolymer.
