Lysine (C6H14N2O2) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Lysine is 146.18848 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Lysine [C6H14N2O2] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Lysine molecule.
From the chemical formula, you will know different atoms and their number in a Lysine molecule. The chemical formula of Lysine is C6H14N2O2. From the chemical formula of Lysine, you can find that one molecule of Lysine consists of six Carbon (C) atoms, fourteen Hydrogen (H) atoms, two Nitrogen (N) atoms, and two Oxygen atoms.
Step 2: Find out the atomic weights of each atom (from the periodic table).
Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Nitrogen (N): 14.00674 (Ref: Jlab-ele007)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)
Step 3: Calculate the total weight of each atom in a Lysine molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Lysine: 6
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Lysine 12.0107 x 6 = 72.0642
Number of Hydrogen atoms in Lysine: 14
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Lysine: 1.008 x 14 = 14.112
Number of Nitrogen atoms in Lysine: 2
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Lysine: 14.00674 x 2 = 28.01348
Number of Oxygen atoms in Lysine: 2
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Lysine: 15.9994 x 2 = 31.9988
Step 4: Calculate the molecular weight of Lysine by adding up the total weight of all atoms.
Molecular weight of Lysine: 72.0642 (Carbon) + 14.112 (Hydrogen) + 28.01348 (Nitrogen) + 31.9988 (Oxygen) = 146.18848
So the molecular weight of Lysine is 146.18848.
