Nitrogen is a diatomic molecule in the VA family on the periodic table. Nitrogen has five valence electrons, so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond.
When different macronutrients (e.g., carbohydrates) are metabolized, they yield different amounts of energy, commonly measured in kilocalories.
They are given by the following conversion factors:
carbohydrates = 4 kcal/g
protein = 4 kcal/g
fat = 9 kcal/g
If the slice of pizza contains 29 g carbohydrates, that means there are 4 kcal/g × 29 g = 116 kcal from carbohydrates. It contains 13 g protein, so there are 4 kcal/g <span>× 13 g = 52 kcal from protein.
The total number of kilocalories is 280, of which we have accounted for 168 (116+52). 280–168=112 kcal.
So, there are 112 kcal from fat. Using our conversion factor, 112 kcal </span><span>× 1 g/9 kcal = 12 g fat.</span>
