tyrosine

 [ti´ro-sēn]
a naturally occurring, nonessential amino acid present in most proteins and synthesized metabolically from phenylalanine. It is a precursor of melanin, catecholamines, and thyroid hormones.

ty·ro·sine (Tyr, Y),

(tī'rō-sēn, -sin),
2-Amino-3-(4-hydroxyphenyl)propionic acid; 3-(4-hydroxyphenyl)alanine; the l-isomer is an α-amino acid present in most proteins.

tyrosine

(tī′rə-sēn′)
n.
A nonessential amino acid, C9H11NO3, that is produced in the body from phenylalanine and is a precursor of melanin and of several neurotransmitters and hormones, such as epinephrine and thyroxine.

(Tyr, Y) (tī'rō-sēn)
An α-amino acid present in most proteins.
