The molecular weight of Glutamine [C₅H₁₀N₂O₃] is 146.14518.

Glutamine (C₅H₁₀N₂O₃) is an organic compound of four elements: Carbon, Hydrogen, Nitrogen, and Oxygen. The molecular weight of Glutamine is 146.14518 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Glutamine  [C₅H₁₀N₂O₃] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Glutamine molecule.
From the chemical formula, you will know different atoms and their number in a Glutamine molecule. The chemical formula of Glutamine is C₅H₁₀N₂O₃. From the chemical formula, you can find that one molecule of Glutamine consists of five Carbon (C) atoms, ten Hydrogen (H) atoms, two Nitrogen (N) atoms, 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 Glutamine molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Glutamine: 5
Atomic weight of Carbon (C): 12.0107
Total weight of Carbon atoms in Glutamine: 12.0107 x 5 = 60.0535

Number of Hydrogen atoms in Glutamine: 10
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Glutamine: 1.008 x 10 = 10.08

Number of Nitrogen atoms in Glutamine: 2
Atomic weight of Nitrogen (N): 14.00674
Total weight of Nitrogen atoms in Glutamine: 14.00674 x 2 = 28.01348

Number of Oxygen atoms in Glutamine: 3
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Glutamine: 15.9994 x 3 = 47.9982

Step 4: Calculate the molecular weight of Glutamine by adding up the total weight of all atoms.

Molecular weight of Glutamine: 60.0535 (Carbon) + 10.08 (Hydrogen) + 28.01348 (Nitrogen) + 47.9982 (Oxygen) = 146.14518

So the molecular weight of Glutamine is 146.14518.
