homogentisicadj.

/hɒməʊdʒɛnˈtɪsɪk/

Etymology: translating German homogentisinsäure homogentisic acid (Wolkow & Baumann 1891, in Zeitschr. f. Physiol. Chem. XV. 245), < homodynamous adj. (b) at homo- comb. form 1 + gentisic adj.

homogentisic acid n. a crystalline compound, C₈H₈O₄, which oxidizes to a black compound in air, is an intermediate in the metabolism of aromatic amino-acids, and is excreted in large amounts by persons with alkaptonuria; alkapton, 2,5-dihydroxyphenylacetic acid.

1969 Listener 16 Jan. 74/3 It's now known that not only do one's genes decide whether one is to have red hair, double-jointed thumbs or a Hapsburg lip, but they also decide whether one is going to excrete homogentisic acid or not.
