>Peptiglycons are found in the cell walls of prokaryotic cells. Proteins are polymers of aminoacids arranged in a specific sequence which is decided by the genetic code present in the DNA molecule. The polypeptide chain in a protein may be straight (primary structure) or may form helical coils (sec..

Internal Energy - Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or intrinsic energy. It is represented by the..

Summary - Nitrogen is the first member of group VA. Nitrogen has 5 electrons in its valence shell. It has a valency of 3 with respect to hydrogen and a valency upto 5 with respect to oxygen. It is a non-metal and its oxides are acidic in nature. Nitrogen is an important component..

A metal ion system in which the metal is in equilibrium with its own ions in solution is called a metal electrode. Example: Zn rod is dipped in ZnSO 4 solution constitutes a Zn electrode, which is represented as Zn/Zn + 2 . When equilibrium is established between a gas and its ions in solution a ga..
