What is "hippuric acid"

Hippuric \Hip*pu"ric\, a. [Gr. "i`ppos horse + o"y`ron urine: cf. F. hippurique.] (Physiol. Chem.) Obtained from the urine of horses; as, hippuric acid.

Hippuric acid, a white crystalline substance, containing nitrogen, present in the urine of herbivorous animals, and in small quantity in human urine. By the action of acids, it is decomposed into benzoic acid and glycocoll.

n. (context organic compound English) A benzoyl derivative of glycine; it occurs in the urine of herbivores

Hippuric acid ( Gr. hippos, horse, ouron, urine) is a carboxylic acid found in the urine of horses and other herbivores. Hippuric acid crystallizes in rhombic prisms which are readily soluble in hot water, melt at 187 °C, and decompose at about 240 °C. High concentrations of hippuric acid may also indicate a toluene intoxication; however, scientists have called this correlation into question because there are other variables that influence levels of hippuric acid. When many aromatic compounds such as benzoic acid and toluene are taken internally, they are converted to hippuric acid by reaction with the amino acid, glycine.
