Glucose Tyrosinase, Tyrosine and the Pescatarian Diet
Tyrosine is a non-essential amino acid, meaning the human body can produce it from phenylalanine, another amino acid. It plays a critical role in the production of neurotransmitters such as dopamine and norepinephrine, as well as hormones like thyroid hormones. Tyrosine is found in high-protein foods and is also available as a dietary supplement. Commercially, it can be hydrolyzed from bird feather keratin or milk casein, which may concern those with specific dietary restrictions.
