Which one of the following statements is not correct regarding the amino acid, tyrosine, present in protein rich foods?
- AIt can help increase energy levels.
- BIt can cope with emotional and environmental stress.
- CIt can combat depression.
- DIt can protect against free radicals responsible for ageing.
Show answer and explanation
Correct answer: (d) It can protect against free radicals responsible for ageing.
Explanation
Tyrosine is an amino acid that boosts energy levels, helps cope with stress, and combats depression by producing brain chemicals like dopamine.
Protection against free radicals responsible for ageing is the role of antioxidants (e.g. vitamins C and E), not tyrosine.
Thus the statement about free-radical protection is the incorrect one.
