Tyrosine metabolism is the process by which the amino acid tyrosine is broken down and utilized by the body. It begins with the conversion of phenylalanine, another amino acid, into tyrosine. This process is crucial for producing important substances like dopamine, norepinephrine, and epinephrine, which are neurotransmitters that help regulate mood, stress, and other bodily functions. Once formed, tyrosine can be further metabolized into various compounds. It can be converted into melanin, the pigment responsible for skin and hair color, or it can be used to synthesize proteins. Proper tyrosine metabolism is essential for maintaining overall health and well-being.
