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.
ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. It is dubbed as the universal unit of energy for living organisms. Without ATP, various metabolic activities in the human body cannot take place. ATP consists of one adenine molecule and three phosphate molecules. These molecules are produced through various processes including cellular respiration and phosphorylation. ATP molecules are called the drivers of cellular metabolism. They carry the energy needed by a particular cellular activity. Another important thing about this molecule is that it is recyclable.
