Figure 15.16 Some modification methods that are useful for fullerenes also can be used with carbon nanotubes. The reaction of an N-glycine compound with an aldehyde derivative can result in cycloaddition products, which create pyrrolidine modifications on the nanotube surface.

Evidence of interactions of actinides with rhodotorulic acid and 2,3-dihydroxy-benzoyl-N-glycine is presented in Figs. 1 and 2. In Fig. la the distribution of plutonium between citric acid, fractions 22—28, and transferrin, fraction 14-18, (the evi-... 

The ability of 2,3-dihydroxybenzoyl-N-glycine to form a stable complex with plutonium is demonstrated in Fig. 2. In the absence of 2,3-dihydroxybenzoyl-N-glycine plutonium nitrate hydrolyzed and could not be eluted from the column. In the presence of 2,3-dihydroxybenzoyl-N-glycine the plutonium recovery averaged 80%. 

Fig. 2. Ultrafiltered plutonium nitrate (50 pi) was added to an aqueous solution of 2,3-dihydroxy-benzoyl-N-glycine (0.05M), pH 3.5. The resulting solution (1.5 ml) was eluted from Sephadex G-50 (0.9 x 60 cm) with 0.1M 2-amino-2-hydroxymethylpropane-l,2-diol/lM NaCl, pH 8.0...

It was expected that if amino acids were used instead of hydroxylamine, peptides would be formed in the experiments of aminoacyl hydroxamate formation 31). However, when glycine is warmed with ATP and MgCl2 in the solid state (derived from the solution), peptide is not formed but adenylyl-(5 -> N)-glycine (gly-N-pA) is formed34> 35). When imidazole is used instead of amino acids, adenosine 5 -phosphorimidazolide (ImpA) is formed in a few percent yield 34). 

Figure 20.4 The Picou and Taylor-Roberts model for studying whole-body protein turnover. Nitrogen enters the metabolic pool via I and C, and exits via Er and S. [1 N]-glycine is infused continuously, and represents the label for overall nitrogen entry into the pool.

V in recent and -0.24 V for two-year-old needles, V. myrtillus -0.26 and D.flexuosa -0.165 V), similar to values for polycarboxylate ligands rather than amino acids. This suggests that, for a variety of only loosely related plant species which in addition are supported by quite unlike kinds of mykorrhiza, sigifificant parts of transport and metal fractionation occur beyond the roots (where the doubly labeled C- + N-glycine was recovered (Nasholm et al. 1998)), with the root/shoot interfacial region being the most probable bottleneck or site of control.

It is emphasized that accurate interatomic distances are a prerequisite to achieving the three-dimensional structure of peptides, proteins and macromolecules. A careful evaluation of the following several points is the most important step to obtaining reliable interatomic distances by the REDOR experiment, although they have not always been taken seriously into account in the early papers. In practice, it is advisable to employ a standard sample such as [1- C, N]glycine [18], whose C-N interatomic distance is determined to be 2.48 A by a neutron diffraction study, to check that the...

Bien et al. (1953) studied one normal subject, and found an increase in renal uric acid excretion of 62 mg/day by nearly doubling the protein content of the diet. At the same time there was an increase in incorporation of N-glycine into uric acid, which was attributed to an increased endogenous uric acid synthesis.
