This moment version expands at the prior variation with new chapters which are appropriate for newbies, in addition to extra specific chapters that hide protein balance and garage, fending off proteolysis in the course of chromatography, protein quantitation tools together with immuno-qPCR, and the demanding situations that scale-up of construction poses to the investigator.

O-Cresol (X) is oxidized to a slight extent to a substance thought to be methylhydroquinone (XI). Salicylic acid, a possible metabolite, was not found. p-Cresol (XII) was also partly oxidized, but in this case the side chain was attacked producing p-hydroxybenzoic acid (XIII). 5°) of p-tolyl glucuronoside and p-tolyl sulfuric acid (XIV) from the urine of dogs fed p-cresol. They formulated the salt as follows: CH » C } 0-CHCCHOH)sCHCOO- Ba-OS0 2 0^}cH, χπε Halogenated phenols, used in the past as external disinfectants, now ap­ pear to act also as powerful internal disinfectants.

09°) which has been isolated from the urine of rabbits after ingestion of the alcohol (95). Trichloroethyl alcohol appears to be excreted partly unchanged and partly as trichloroethyl glucuronoside (urochloralic acid) (216). Secondary Alcohols. In addition to reporting that primary alcohols cause an increased excretion of glucuronic acid, Neubauer (299) claimed a similar effect after administration of isopropyl, sec-butyl and seooctyl alcohols. In contradiction, Neymark (310) has reported the quantitative transformation of isopropyl alcohol to acetone in the dog.

Syringaldehyde (LII) is converted in rabbits to a glucuronoside having two carboxyl groups, probably 3,5-dimethoxy-4-glucuronosidobenzoic acid (LIII), the glucuronoside of syringic acid (447). CHO CHaO COOM CH 3 OH HC CH30-*Y^OCH3 OC e H 9 O e IHE p-Tolualdehyde, anisaldehyde, veratraldehyde, piperonal, and o- and p-aminobenzaldehyde are all oxidized to the corresponding acids, which form conjugates of glucuronic acid in the rabbit (150, 372). Mixed ketones follow two courses of metabolism in the animal body.
