Triglycine

DTGS = deuterated triglycine sulfate KRS — 5 = mixed thallium bromide-iodide LT = lithium tantalate MCT = mercury cadmium telluride and OPO = optical parametric oscillator. 

Huot et al. [38] used affinity chromatography to identify and partially purify an amiloride-binding protein with characteristics of the renal brush border Na /H exchanger. The high-affinity amiloride analog A35 (5-A-(3-aminophenyl)amiloride) was coupled to Sepharose CL-4B through a triglycine spacer. Rabbit renal brush border membranes were solubilized with 0.6% Triton X-100, incubated with the...

Direct amide formation in aqueous solution between carboxylic acids and amines can occur and the rates are first order in the anion of the acid and the basic form of the amine (Eq. 9.12).23 The second-order rate constant is independent of the acidity of the medium. The condensation reaction of glycine to form di- and triglycine occurs in aqueous solution... 

The source is usually a temperature-stabilized ceramic filament operating around 1500K. The detector in FTIR is usually a deuterium triglycine sulphate (DTGS) detector, although in RAIRS experiments the liquid nitrogen-cooled mercury cadmium telluride (MCT) detector is employed.

DR. KENNETH KUSTIN (Brandeis University) Some years ago, you studied reactions of the type MX + Y = MY + X and found some interesting effects, such as chain reactions and phenomena of that sort. You also found that there was autocatalysis of such ligand substitution reactions by, I believe, triglycine. Has that turned up again Are other tripeptides or polypeptides autocatalytic How does that fit in with the base catalysis concept ... 

DR. MARGERUM Yes, it does turn up in a number of instances. The example you are talking about was an EDTA reaction with a copper triglycine in which the released triglycine catalyzed the substitution of the EDTA. This resulted from the fact that the bis-triglycine complex is faster to undergo substitution than is the mono complex. The released triglycine formed a bis complex and the EDTA then attacked that. 

Pyroelectric detectors depend on the use of a thin slice of ferroelectric material (deuterated triglycine sulfate [DTGS], Figure 5.6, is the standard example) - in which the molecules of the organic crystal are naturally aligned with a permanent electric dipole. The thin slab is cut and arranged such that the direction...
