Morphine and morphine 3-p-D-glucuronide were separated on two different 4.6-mm-diameter X 50-mm-long columns with 3-p.m particles.29 Column A was Cl8-silica run at 1.4 mL/min and column B was bare silica run at 2.0 mL/min. 

Coumarins also have a C6-C3 skeleton, but they possess an oxygen heterocycle as part of the C3-unit. There are numerous coumarins, many of which play a role in disease and pest resistance, as well as UV-tolerance. The coumarin umbelliferone (1.21) is popular in enzyme assays. Umbelliferone esters can be used as a substrate for non-specific esterase enzyme assays and in fluorescent immunoassays (Jacks and Kircher, 1967). In order to quantify the enzyme activity of the popular reporter gene P-glucuronidase (GUS), plant extracts can be incubated with 4-methylumbelliferyl P-D-glucuronide (4-MUG 1.22), which upon hydrolysis...

Chemotaxis experiments (see Note 2) Use blind well Boyden chambers, that contain a volume of 100 pL in the lower compartment (Costar, Bodenheim, Germany). As filters use selfpunched (7 pm punch) polyvinylpyrrolidone containing polycarbonate filters (pore size 3 mm, Costar), which prior to use need to be washed with 1 M NaOH in 50 % (v/v) aqueous ethanol for 7 min followed by three washes in water (see Note 3). Use p-nitrophenyl-p-D-glucuronide (Sigma) at 10 mM in 0.1 M aqueous sodium acetate, pH 4.0, for p-glucuronidase detection (see Note 4). 

Fig. 4 Formation of uridine diphosphate glucuronic acid (UDP-GA) and its conjugation with clofibric acid. Inversion takes place during conjugation, the a-D-glucuronic acid forming a P-D-glucuronide. At a more alkaline pH, such glu-curonides may undergo intramolecular rearrangement to forms resistant to enzymic hydrolysis by P-glucuronidase.

Rate laws, however, can only establish the composition of the ratedetermining transition state, not its structure, and in particular they cannot distinguish between tautomers. 2 -Naphthyl p-D-glucuronide has a similar rate law to salicyl (3-glucoside, but the molecular events giving rise to it are different (Figure 3.17). If feg is the rate constant for the pH-independent part of the...
