Like many other members of the B-vitamin family, Niacin is well-known for its role in energy metabolism (breaking down substances in the body to yield energy). Actually, niacin plays a part in the energy metabolism of all cells in the body. Another benefit of water-soluble vitamin is its versatility.
Adenosine triphosphate (ATP) , the energy currency or coin of the cell pictured in Figfures 1 and 2, transfers energy from chemical bonds to endergonic (energy absorbing) reactions within the cell.nergy is stored in the covalent bonds between phosphates, with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This covalent bond is known as a pyrophosphate bond.
Animal cells get energy from food, while plant cells get energy from sunlight. All cells use chemical energy. â¢ Chemical energy is the energy stored in the bonds between atoms of every molecule. To stay alive, cells must be able to release (not create) the chemical energy in the bonds. â¢ A major source of energy for most cells is stored in a sugar molecule called glucose. When you need energy, cells release chemical energy from glucose. You need food energy to run, walk, and even sleep.
