Calculation Formula
From Protein:
Phenylalanine (mg) = Protein (g) × 50
Phe Units = Phenylalanine (mg) ÷ 25
From Phenylalanine:
Protein (g) = Phenylalanine (mg) ÷ 50
Phe Units = Phenylalanine (mg) ÷ 25
From Phe Units:
Phenylalanine (mg) = Phe Units × 25
Protein (g) = Phenylalanine (mg) ÷ 50
About PKU
Phenylketonuria (PKU) is a rare genetic disorder that affects the body's ability to break down the amino acid phenylalanine. People with PKU need to carefully monitor their phenylalanine intake through diet. This calculator helps convert between protein amount, phenylalanine content, and Phe units to assist with dietary planning.
