Thus, 1 kilocalorie (kcal) = 1000 calories (cal). Oxidation of one gram of carbohydrate yields approximately 4 kcal of energy. This is equivalent to a thousand calories (abbreviated "cal") or one kilocalorie (kcal). Citric acid has 247 kcal per 100 g. The variety is rich in calories with up to 5 kcal per particle of rice. Alcohol in food contains 7 kcal/g.. That implies a stabilization energy of 3.5 kcal/mol. These reactions are exergonic by 216 and 209 kcal/mol, respectively. Within the European Union, both the kilocalorie ("kcal") and kilojoule ("kJ") appear on nutrition labels. Maltitol provides between 2 and 3 kcal/g. For example, H(CHBCl) has an experimentally determined GPA of 241 kcal/mol. E-cyclooctene has a highly twisted double bond resulting in a strain energy of 17.9 kcal/mol. LiP has a MolDock score of -156.03 kcal/mol. As a condiment, mustard averages about 5 kcal per teaspoon. This places the resonance stabilization at around 6 kcal/mol.
