tyrosine

Etymology

From Ancient Greek τῡρός (tūrós, “cheese”) + -ine; surface analysis is nearly, although not quite, tyro- + -ine (i.e., semantically valid although morphologically amiss; tyro- itself is derived from Ancient Greek τῡρός (tūrós, “cheese”)).

noun

1. (biochemistry) A nonessential amino acid 2-amino-3-(4-hydroxyphenyl)propanoic acid found in most animal proteins, especially casein
