666 METABOLISM 



Glycuronic acid, the other substance used for detoxication processes, 

 is of the nature of a dextrose molecule with the one end-group oxidized 

 to carboxj^l (CHO - (CHOH) 4 - COOH). It is probably produced under 

 normal processes of metabolism in the animal body, but is destroyed 

 except when such poisonous substances as camphor, chloral hydrate or 

 certain aromatic alcohols are given, when it is used for the purpose of 

 detoxicating them. The resulting glycuronates have reducing powers 

 and may be confused with glucose when present in large amount. Gly- 

 curonates may be distinguished from glucose in the urine (1) because 

 they are levorotatory, and (2) because they do not ferment. The free 

 acid itself, however, is dextrorotatory.
