Para xanthin

(par-az-an' '-thin), A leukoma in discovered in and since shown to be a normal constituent of urine, though present in very small quantities. It was formerly called urotheobromin. Para xanthin is isomeric with theobromin, also with dioxy-dimethyl-purpurin; it is, therefore, a dimethyl-xanthin. It crystallises readily in characteristic flat, somewhat irregular, sixsided tables when its solutions are slowly evaporated, or in needles if rapidly evaporated. See Leukomaim, Paraxial (par-aks'-e-al). Lying near the axis of the body. A descriptive term applied to certain muscles, which, in the Bitiiattt represented by the intercostal and abdominal muscles.
