The molecular weight of Tyrosine [C9H11NO3] is 181.18924.
Tyrosine (C5H11NO3) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Tyrosine is 181.18924 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.
CALCULATION PROCEDURE: Tyrosine [C9H11NO3] Molecular Weight Calculation
Step 1: Find out the chemical formula and determine constituent atoms and their number in a Tyrosine molecule.
From the chemical formula, you will know different atoms and their number in a Tyrosine molecule. The chemical formula of Tyrosine is C9H11NO3. From the chemical formula of Tyrosine, you can find that one molecule of Tyrosine consists of five Carbon (C) atoms, eleven Hydrogen (H) atoms, one Nitrogen (N) atom, and three 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 Tyrosine molecule by multiplying its atomic weight by its number.
Number of Carbon atoms in Tyrosine: 9
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Tyrosine: 12.0107 x 9 = 108.0963
Number of Hydrogen atoms in Tyrosine: 11
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Tyrosine: 1.008 x 11 = 11.088
Number of Nitrogen atoms in Tyrosine: 1
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Tyrosine: 14.00674 x 1 = 14.00674
Number of Oxygen atoms in Tyrosine: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Tyrosine: 15.9994 x 3 = 47.9982
Step 4: Calculate the molecular weight of Tyrosine by adding up the total weight of all atoms.
Molecular weight of Tyrosine: 108.0963 (Carbon) + 11.088 (Hydrogen) + 14.00674 (Nitrogen) + 47.9982 (Oxygen) = 181.18924
So the molecular weight of Tyrosine is 181.18924.
