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.
As rotation continues, the molecule comes to the anti conformation, which is the most stable since the substituents are staggered and the methyl groups are as far away from each other as possible. An energy diagram is a graph which represents the energy of a molecule as a function of some changing parameter.n one case, the dihedral angle is 0Â° and the hydrogens on the first carbon line up with or eclipse the hydrogens on the second carbon. When the dihedral angle is 0Â° and the hydrogens line up perfectly, ethane has adopted the eclipsed conformation (Figure 2).
