Macromolecules

"Macromolecules unit the biological molecules synthesized by the plants and animals to satisfy their metabolic and energy wishes, and to carry out their day to day activities during a} very ancient manner. The animal bodies, together with each physical body also because the bodies of any experimental animals like mice and rats include numerous macromolecules. They’re classified into nucleic acids (both desoxyribonucleic acid and RNA), proteins, glucides and lipids, consistent with their chemical structures. These macromolecules are often incontestable by specific histochemical staining techniques for several molecules like Feulgen reaction (Feulgen and Rossenbeck 1924) that stains the complete desoxyribonucleic acid contained within the cells. every compounds of macromolecules like desoxyribonucleic acid, RNA, proteins, glucides, lipids are often incontestable by several specific histochemical staining and such reactions are often quantified by microscpectrophotometry victimisation specific wave-lengths demonstrating the whole quantity of several compounds. To the contrary, radioautography can entirely demonstrate the contemporary synthesized macromolecules like artificial desoxyribonucleic acid or polymer or proteins relying upon the RI-labeled precursors incorporated specifically into these macromolecules like 3H-thymidine into desoxyribonucleic acid or 3H-uridine into polymer or 3H-amino acid into proteins.
