Final answer:
Phenex is a milk substitute that contains casein hydrolysate, providing 0.4% phenylalanine.
Step-by-step explanation:
The statement is true. Phenex is a milk substitute that contains casein hydrolysate, a protein source derived from milk. Casein hydrolysate is a partially broken down form of casein, which is a protein found in milk. It is commonly used in milk substitutes for individuals who are lactose intolerant or have a milk allergy.
Phenex provides 0.4% phenylalanine because casein hydrolysate contains this essential amino acid. Phenylalanine is necessary for the production of other important molecules in the body, such as neurotransmitters.
Overall, Phenex is a milk substitute that contains casein hydrolysate, providing 0.4% phenylalanine.
