Pertaining to, or designating, a complex nitrogenous acid, isomeric with uric acid.

An artificial nitrogenous base, isomeric with urea, and forming a white crystalline substance; -- called also isuretine.

in water, with an intensely sour taste and strong acid reaction. There are at least three isomeric modifications all having the formula C3H6O3.

A complex, oily, nitrogenous base, isomeric with nicotine, and obtained by the reduction of certain derivatives of the pyridine group.

Connection with, or affinity to, one variety of isomerism, characteristic of the benzene compounds; -- contrasted with meta- or para-; as, the ortho position; hence, designating any substance showing such isomerism; as, an ortho compound.
